[akregator] [Bug 393672] akregator crashing on startup

--- Comment #1 from Bernd Steinhauser  ---
I updated Qt from 5.9 to 5.10 and with that akregator works again, so I think
this might have been caused by a upstream bug in Qt.
Feel free to close it.

[akregator] [Bug 393672] New: akregator crashing on startup

[Bernd Steinhauser]

https://bugs.kde.org/show_bug.cgi?id=393672

Bug ID: 393672
   Summary: akregator crashing on startup
   Product: akregator
   Version: unspecified
  Platform: Exherbo Packages
OS: Linux
Status: UNCONFIRMED
  Severity: normal
  Priority: NOR
 Component: general
  Assignee: kdepim-bugs@kde.org
  Reporter: li...@bernd-steinhauser.de
  Target Milestone: ---

Since 16.04 (maybe in combination with a KF5 update, can't tell), akregator is
crashing on me.
I've already tried with a clean config, because at first I thought it was
config-related.

If I start it from within konsole, I get these messages:
[1:1:0100/00.357507:ERROR:broker_posix.cc(41)] Invalid node channel message
[1:1:0100/00.358594:ERROR:broker_posix.cc(41)] Invalid node channel message

QSocketNotifier: Invalid socket 76 and type 'Read', disabling...
QSocketNotifier: Invalid socket 71 and type 'Read', disabling...
zsh: suspended (signal)  akregator

(the above file existent)
Hence, I think it might be related to kdeinit5 or rather the socket it's trying
to connect to, but I'm not sure.
If I start Akregator from another user that does have access to X11 (as in: can
show a window), but doesn't have access to kdeinit and dbus, akregator will
start and not crash (it won't work either, though, because of the missing
connectivity).

[akregator] [Bug 381929] Feeds list gets corrupted when akregator is restored on log in

[Bernd Steinhauser]

https://bugs.kde.org/show_bug.cgi?id=381929

--- Comment #10 from Bernd Steinhauser  ---
(In reply to Christophe Giboudeaux from comment #9)
> did it start refreshing a feed when you closed it ?

Sorry, did not pay attention to that, so can't really tell.

Afterwards, I did try to enforce that by hitting the fetch all feeds button and
then closing Akregator, but it didn't trigger this.

[akregator] [Bug 381929] Feeds list gets corrupted when akregator is restored on log in

[Bernd Steinhauser]

--- Comment #8 from Bernd Steinhauser  ---
Just tried again and it's definitely not only on log in.
Took me maybe 10 restarts of Akregator until I got the message that the feed
list is corrupted.
In that case it also told me that Akregator didn't close properly, although
there was no indication of a crash (no coredump, no bug message etc.).

[akregator] [Bug 381929] Akregator looses feed list

[Bernd Steinhauser]

https://bugs.kde.org/show_bug.cgi?id=381929

--- Comment #6 from Bernd Steinhauser  ---
Maybe I should add that I've seen the corruption after quitting Akregator only
once (out of 10-20 times), it seems much more unlikely.
When you don't specifically close Akregator before reboot, it seems much more
likely that the list gets corrupted (maybe 2 out of 3 times).

To me this smells like some sort of race condition.

> d) using the menu File - Quit
I chose
e) right-click on the tray icon and choose Quit, which should be the same
thing. Next start of Akregator (without rebooting) -> list trashed

Just wanted to add that I observed this bug as well when I close Akregator
manually.

Possibly a duplicate of bug 381822.

Anyway, I started to see this problem as well and it started exactly after I
upgraded Qt from 5.8.0 to 5.9.1.
I did rebuild Akregator and it's dependencies (up from Qt, obviously), but that
didn't help either.
