Status changed to 'Confirmed' because the bug affects multiple users.

Happened again, but now it refers to icon instead of font.

Not sure if I'm adding my report to the correct bug, but still...

When I lock the screen or put the computer to sleep, gnome-shell crashes. The crash might be related to extensions, as I was unable to reproduce the crashes when extensions were disabled.

Nontheless, Gnome-shell should not crash or be unable to wake up from suspend because of a faulty extension.

I'm not really sure if I am attaching the appropriate information, please, let me know if more information is needed. (please, mention also how to obtain it)

Thank you for your work!

with regards,

Tomas Kaluza

Hey people, are you using gTile as well? This is what's causing the crash for me (bug 1871684).

https://github.com/gTile/gTile/issues/124

No, I'm not using gTile. To Lock the screen and log in also works OK. My gnome-shell crashes don't happen that often and I haven't found a way to reproduce the crash.

Yes, @juliank ! I am also suspecting gTile as the culprit for the crashes. I haven't had enough time to make sure thought.

The bug I reported is: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1871063

Thank you for the link to the github issue!

Tracking upstream in: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2541

In my case it did appear to be gTile related also. Just manually disabling the extension on the gnome extensions panel was also sufficient to trigger a crash (presumably triggering the same path as when the screen lock was activated). Presumably other extensions using libst can have the same effect.

This bug was fixed in the package gnome-shell - 3.36.2-1ubuntu1

I don't have a standard installation of Ubuntu 20.04 any longer. It's now
updated with kernel 5.6.7-050607-generic x86_64 and I'm also using
the oibaf-ppa.
I tried clicking multiple times in appindicators in the system tray, but I
didn't get any error.
I run Fedora 32 on this computer too and I think I got this error also on
Fedora 32 before it was upgraded to gnome-shell 3.36.2.
I have these extensions installed: AlternateTab, Dash to Panel, OpenWeather
and Sensory Perception

Hello Per-Inge, or anyone else affected,

Accepted gnome-shell into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/gnome-shell/3.36.2-1ubuntu1~20.04.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-focal. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

I installed the gnome related components from proposed, but this isn't on a
standard installation I'm using the oibaf ppa (4.6 Mesa 20.2.0-devel
(git-d510974 2020-05-06 focal-oibaf-ppa) and kernel 5.6.7-050607-generic
x86_64. After the update the Gnome desktop is Gnome 3.36.2.
This problem doesn't happen often, but I will use this configuration for
some time. Alternatively I also use a system on other hardware with Groovy
Gorilla. This system don't have any kernel or graphic driver changes.

Although we recommend NOT using the oibaf PPA (it is unsupported and frequently buggy), it also shouldn't matter for this bug.

No error reported for the SRU or groovy version for this crash at https://errors.ubuntu.com/problem/7235aacf0ac9572c674e49ffcc32ddb01d46a0f0

I reinstalled and got a crash after suspend. It might be bug 1877774, but I
made a new one.
