[Andrea Azzarone]

So for the people that were affected by this crash before and willing to
help, can you please install this ppa
https://launchpad.net/~azzar1/+archive/ubuntu/gnome-shell-check-nan-2
and wait for the crash to happen and then send me the crash file in
/var/crash? There was a problem with apport until few days ago, that's
why crash file were not being collected.

[dino99]

@thejoe

Questions about that install:
- it seems to be a 'rolling' install; many dist-upgrade done
"InstallationDate: Installed on 2015-08-21 (742 days ago)
InstallationMedia: Ubuntu-GNOME 15.10 "Wily Werewolf" - Alpha amd64 "

- does it has been cleaned ? (using gtkorphan & bleachbit (as root))

- which theme(s) are used ? Have you tried resetting to the default ones ?
( often old settings can seriously disturbe the system with their recent 
changes)

That's weird. Please revert the PPA using ppa-purge. I need to understand
why nothing shows up in /var/crash.

[Andrea Azzarone]

@thejoe (or others interested to help)

$ sudo add-apt-repository ppa:azzar1/gnome-shell-check-nan-2
$ sudo apt update
$ sudo apt upgrade

Reboot to make sure you start the new gnome-shell. Please note that this
ppa does not contain a fix but it will make sure we collect more info in
order to debug the issue. In case you get a crash, apport should do the job
otherwise ping me on irc (andyrock) and will help you to collect all the
required info. Thanks!

[Desktop-packages] [Bug 1714542] Re: gnome-shell crashed with SIGSEGV in st_theme_node_reduce_border_radius() from st_theme_node_paint_borders() from st_theme_node_paint()

[Andrea Azzarone]

@thejoe (or others interested to help)

$ sudo add-apt-repository ppa:azzar1/gnome-shell-check-nan-2 
$ sudo apt update
$ sudo apt upgrade

Reboot to make sure you start the new gnome-shell. Please note that this
ppa does not contain a fix but it will make sure we collect more info in
order to debug the issue. In case you get a crash, apport should do the
job otherwise ping me on irc (andyrock) and will help you to collect all
the required info. Thanks!

For the moment we can distro patch my workaround to avoid crashing. I'm
already working to understand the true problem and propose the proper
fix. For the moment it's better to avoid the crash.

Hi, my fix is just a workaround. To properly fix the bug we need your help.
I'll pass you a PPA with a customized version of gnome shell that should
give us more insights on what's really going on.

[Joe Barnett]

I'm happy to help.  I've applied the patch from the gnome bug to a local
package build.  Haven't seen the crash since but only been a day or so
(was crashing on the order of once a week prior)

[Desktop-packages] [Bug 1714542] Re: gnome-shell crashed with SIGSEGV in st_theme_node_reduce_border_radius() from st_theme_node_paint_borders() from st_theme_node_paint()

[Joe Barnett]

This appears to happen much more with the experimental mutter fractional
scaling support turned on and scaling set to 150% (and font scaling set
to 100%), but also happens without that enabled.  Without it enabled, I
have scaling set to 100%, but font scaling set to 150%.
