gnome-software crashed with SIGSEGV in gs_flatpak_app_matches_xref()

[Alfred E. Neumayer]

Happened when opening GNOME Software (pretty sure it was already running as a service after login).
Did an apt+snap+flatpak update before that.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

Note that the issue is in the flatpak plugin which is not installed by default on Ubuntu
