gnome-shell crashes when extension <email address hidden> is loaded

[Dave Goldsbrough]

Had a few gnome-shell problems since 20.04 install.
Usually, just did the auto send thing, but this time thought it best to do a manual report.
Not much I can add though.

I do see things like these in the reports from time to time

Invalid core dump: BFD: warning:/tmp/apport_core_7buvs9st is truncated:expected core file size >=582705152, found:11411

Firstly please uninstall these extensions:

  '<email address hidden>',
  'applications-overview-tooltip@RaphaelRochet',
  '<email address hidden>',
  '<email address hidden>',
  '<email address hidden>',
  '<email address hidden>'

and restart. Then if the crash still happens please follow these instructions:

  https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment

[Dave Goldsbrough (daveg-k)]

As requested, all extensions quoted uninstalled and all fine. Still fine after a number of reboots.

Decided to re-install each extension one by one.

Tried '<email address hidden>' first and once more a similar crash and as before system was still usable. Uninstalled once more and system was fine once more.

I then proceeded to reinstall these extensions in this sequence, each time followed by shutdown and reboot. All, no problems.

 '<email address hidden>',
  '<email address hidden>',
  'applications-overview-tooltip@RaphaelRochet'

I have decided I can Live without the others and could even live without the successful ones if necessary.

If I should be reporting these extension bugs elsewhere, particularly the BingWallpaper one then please advise.

Happy for this reported bug to be zapped!

[Daniel van Vugt (vanvugt)]

Thanks for figuring that out. Bugs caused by that extension should be reported to:

  https://github.com/neffo/bing-wallpaper-gnome-extension/issues

But also I would still like to find out what the signature of this crash looks like so we can identify it in future. If you can then please follow these instructions:

  https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment

Reinstalled '<email address hidden>' and as expected on a reboot an "Ubuntu has experienced an internal error" box was once more generated.

Ran ubuntu-bug _usr_bin_gnome-shell.1000.crash obtained from /var/crash and all it did was produce another/same(?) "Ubuntu has experienced an internal error" box.

The terminal screen is frozen at this point and a Ctrl-C produces this:-
^CTraceback (most recent call last):
  File "/usr/share/apport/apport-gtk", line 597, in <module>
    app.run_argv()
  File "/usr/lib/python3/dist-packages/apport/ui.py", line 719, in run_argv
    self.run_crash(self.options.crash_file, False)
  File "/usr/lib/python3/dist-packages/apport/ui.py", line 313, in run_crash
    response = self.ui_present_report_details(allowed_to_report)

Tried . https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id but all I get is I do not have permission to see.

I have looked briefly at https://bugs.launchpad.net/ubuntu/+source/apport/+bug/994921 and I am now at a loss as to exactly what to do.

[Daniel van Vugt (vanvugt)]

Thanks for trying. Sounds like more effort than it's worth so forget that. Please remember to just report the crash to the extension developer:
