Bug#810947: kwin-x11: iceweasel locks up when multiple windows restored

Package: kwin-x11
Version: 4:5.5.4-2
Followup-For: Bug #810947

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

When using Plastik window decoration, kwin_x11 locks up when iceweasel
restores multiple windows (tried 3 times in a row today).

After setting window decoration to org.kde.breeze and restarting the session,
iceweasel restores without any problems with kwin_x11.

After latest updates in unstable, had 3 attempts now in a row of logging into
a plasma session, restarting iceweasel and experiencing a kwin_x11 lock-up.

Currently using Plastik window decoration theme, will test with org.kde.breeze 
next.

Version: 4:5.5.4-2
Followup-For: Bug #810947

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

I ran several tests using kernel: 

linux-image-4. 4.4.2-3

   * What exactly did you do (or not do) that was effective (or
 ineffective)?

If I attempted to start iceweasel in a KDE Plasma desktop session straight 
after a reboot using the Plastik window decoration, kwin_x11 would lock
up when iceweasel opened multiple windows. If I quit iceweasel, logged out
of KDE and logged in again, I could start iceweasel without any kwin_x11
problems.

If I attempted to start iceweasel in a KDE Plasma desktop session straight
after a reboot using the org.kde.breeze window decoration, kwin_x11 kept
running fine.

Kernel: Linux 4.4.0+ (SMP w/4 CPU cores)

In that list I see only ONE kernel which was released by Debian and that was 
4.4.0-rc8-amd64 ... which wasn't even a stable kernel.

Bug#810947: kwin-x11: iceweasel locks up when multiple windows restored

[Arthur Marsh]

Package: kwin-x11
Version: 4:5.5.4-2
Followup-For: Bug #810947

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

The last few times kwin_x11 would lock up on the first time running iceweasel
after upgrades of packages used by KDE, but I could quit iceweasel, log out
of the desktop and log back in and iceweasel would start without problem
(possibly due to caching of data used by iceweasel).

However, since the last lot of updates, I had one time where kwin_x11 
segfaulted/restarted and DrKonqi was able to get a usable back-trace:

https://bugs.kde.org/show_bug.cgi?id=359749

that was with exactly the same kernel, and packages as reported in this 
Debian bug report.

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

I was running ok for a few days up until the libstdc++ upgrade associated with
gcc 5.3.1, then tried upgrading kwin-x11 from experimental.

   * What exactly did you do (or not do) that was effective (or

kwin-x11 from experimental runs alright up until about half a minute into
loading iceweasel then locks up, but if I attach gdb to the kwin_x11 process
before starting iceweasel and "continue" it, kwin_x11 runs fine while
iceeweasel runs up multiple windows.

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

After the latest libc6 update, iceweasel restarted fine, so I checked the
libc6 changelog and it referred to bug #814958 

This might be what happened in my case as I have 4 GiB of swap and the
error was that kwin_x11 would lock up at the time that swap started to 
be required.

Bug#810947: kwin-x11: iceweasel locks up when multiple windows restored

[Arthur Marsh]

Package: kwin-x11
Version: 4:5.4.3-1.1
Followup-For: Bug #810947

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

With current kernel and libraries, first time to attempt restoring
iceweasel can still lock up when restoring multiple windows, but after doing
a kill -9 on the locked up kwin_x11 process, allowing iceweasel to restore
windows and shutting things down cleanly, logging out and doing an init 1
to even restart dbus, the next login and iceweasel session restore works 
without any lock-up. 

   * What exactly did you do (or not do) that was effective (or
 ineffective)?

I attempted upgrading kwin-x11 to 4:5.5.4-2 but that would lock up right
at the start before attempting to run any programs like iceweasel or konsole.
(See attached back-trace).

Bug#810947: kwin-x11: iceweasel locks up when multiple windows restored

[Arthur Marsh]

Package: kwin-x11
Version: 4:5.4.3-1.1
Followup-For: Bug #810947

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

The problem still comes and goes semi-randomly when updating various packages.

This time when it locked up I ran gdb on the hung kwin_x11 process and have
attached the log including backtrace.

   * What exactly did you do (or not do) that was effective (or
 ineffective)?
   * What was the outcome of this action?
   * What outcome did you expect instead?

[Arthur Marsh]

Package: kwin-x11
Followup-For: Bug #810947

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
   * What exactly did you do (or not do) that was effective (or
 ineffective)?

After experiences problems as late as yesterday 23 January and applying some
upgrades today, both my usual session and a test account were able to launch
iceweasel with multiple windows (16) being restored without any lock-up of
kwin_x11.

I'll keep checking to see if they problem stays away.

   * What was the outcome of this action?
   * What outcome did you expect instead?

How about following the same suggestions as I did in 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=805341#30 ?

That fixed the issue the previous time ...

IOW: Decide how you want to use your system and if you like to run unstable, 
then get rid of at least the oldstable lines in /etc/apt/sources.list
I wouldn't be surprised if several of your problems are caused by this mess.

And next time when you get an issue, first try to reproduce the problem on 
Debian stock kernel instead of your own compiled one before you report it to 
the BTS.

Bug#810947: kwin-x11: iceweasel locks up when multiple windows restored

[Arthur Marsh]

Package: kwin-x11
Version: 4:5.4.3-1.1
Followup-For: Bug #810947

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

I've commented out oldstable from /etc/apt/sources.list, purged most of the 
packages now listed as obsolete and re-run things with a stock Debian kernel
and am still seeing the same things ie iceweasel locks up when attempting to
restore several windows when starting from the start menu (and this time it
did the same starting from krunner).

If I kill -9 the kwin_x11 process that is the child of the process with the 
command line /usr/bin/kwin_x11 --crashes 1 the iceweasel process continues
and everything loads normally (the /usr/bin/kwin_x11 process continues to 
run and I get the tops of windows still showing).

I'll do a check of starting iceweasel from xfce just to make sure that
still works.

Bug#810947: kwin-x11: iceweasel locks up when multiple windows restored

[Arthur Marsh]

Followup-For: Bug #810947

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
   * What exactly did you do (or not do) that was effective (or
 ineffective)?

I copied my iceweasel profile (~/.mozilla/firefox/profiles.ini and 
~/.mozilla/firefox/vl23iilx.default directory tree) to a new account, 
and started iceweasel in KDE plasma without issue.

I then went to my original account:

cd
cd .mozilla
ls -al

drwxr-xr-x 7 amarsh04 amarsh04 4096 Jan 15 16:34 .

-rw--- 1 amarsh04 amarsh04 6526 Sep 4 2008 oldpluginreg.dat

I moved everything except the empty fonts directory and firefox directory out 
the way, then restarted iceweasel under KDE plasma without problems.

I then quit iceweasel, moved the old directories and mozver.dat and 
oldpluginreg.dat back and was able to start iceweasel under KDE plasma 
without problems.

Even if iceweasel had completely locked up, should it lock up the rest of 
the plasma desktop with it?

Bug#810947: kwin-x11: iceweasel locks up when multiple windows restored

[Arthur Marsh]

Package: kwin-x11
Version: 4:5.4.3-1.1
Followup-For: Bug #810947

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

In previous situation where I had started iceweasel alright with the original 
account and profile, the panel (k start menu, iceweasel icons, clock) had 
locked up and become unresponsive.

After logging out and logging back into the KDE plasma session on the 
original account and restarting iceweasel, iceweasel locked up as before
and locked up the panel (as had happened with every iceweasel lockup before).

Doing an alt-F1 to get another virtual terminal and doing kill -9 on the
kwin_x11 process allowed iceweasel to continue and the panel became responsive
again.

Bug#810947: kwin-x11: iceweasel locks up when multiple windows restored

[Arthur Marsh]

Package: kwin-x11
Version: 4:5.4.3-1.1
Severity: normal

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

Please see bug report #806213 - iceweasel would lock up when restoring 
multiple windows.

   * What exactly did you do (or not do) that was effective (or
 ineffective)?

killing kwin_x11 process after starting plasma desktop, then letting 
iceweasel start up fully, then running kwin_x11 after.

   * What was the outcome of this action?
   * What outcome did you expect instead?

Version: 4:5.4.3-1.1
Followup-For: Bug #810947

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

I found that I could start iceweasel from krunner (alt F2 from plasma
desktop) without issue while kwin-x11 was running.

The problem seems to be a difference between launching iceweasel from
kdeinit5 (plasma start menu) and krunner (alt F2 from plasma desktop).
