Could we get debug logs and a backtrace of the crash please? Otherwise we won't be able to locate it.

I have the same problem since I updated to 3.1.0-20201214.180315.7f4ffd0f7-1.0~focal1 from Ubuntu PPA yesterday. Here is the relevant portion regarding the segmentation fault from the crash report.

Thanks, I'm preparing a PR. It will produce an AppImage it'd be appreciated if you could test it and report here when it shows up.

[er-vin]

AppImage available on #2713 please let us know how this goes. Thanks in advance.

[chli1]

Yes, this version works without problems! Thank you very much for your quick solution!

[er-vin]

Thanks for the confirmation. We'll land it after review then. It will be released in 3.1.1 in a couple of weeks.

Thanks for the quick feedback on #2750 .

However a couple of weeks until a fixed version is available is a long time for such a major issue. :-/

Currently I am not unable to use nextcloud-desktop. The currently available AppImage shows the same issue and in the PPA the last working version 3.0.3 (which is still installed on another machine I didn't update yet) is not longer available.

Is there any workaround to avoid triggering the bug, like deleting the avatar?

[er-vin]

FYI 3.1.1 release preps are going on right now, I've been fast tracking it seeing the amount of affected user. Should be published right in time for xmas.

I'm still baffled this didn't show on any of our test systems and that the bug in the code was present since 3.0.0 but somehow didn't trigger before...

@sercxanto I'm facing the same issue. The fix is already backported to 3.1 so I'm currently using the AppImage built by the corresponding pull request. See AppImage linked here: #2715

I am facing this issue as well:
nextcloud --version Nextcloud version 3.1.0git Git revision 7f4ffd0f72482b6cf42e74335f3a360c3058f023 Using Qt 5.15.2, built against Qt 5.15.2 Using Qt platform plugin 'xcb' Using 'OpenSSL 1.1.1h 22 Sep 2020' Running on openSUSE Tumbleweed, x86_64
ANY workaround I can apply on the data/settings side? Or do I have to switch to AppImage?

[er-vin]

Unfortunately not, it's either AppImage or wait for 3.1.1.

If everything goes well 3.1.1 will be published tomorrow.

[rsudev]

Thank you very much for the speedy reply!
I assume the distro-packages will take even a bit more time, so I'll check out AppImage.

[rsudev]

FYI: The AppImage works for me. Thanks again!

FYI: v3.1.1 works on macos 11.1
Many thanks !
