gnome-shell libmozjs g_closure_unref: assertion closure->ref_count > 0 failed

[Pirouette Cacahuète]

While just using my system, GNOME Shell suddenly disappeared and logs shows:

I'm not sure that assertion is fatal or related to the crash. For example it repeats in:

https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/6767

[Daniel van Vugt (vanvugt)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:

1. Run these commands:
    journalctl -b0 > journal.txt
    journalctl -b-1 > prevjournal.txt
and attach the resulting text files here.

2. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

3. If step 2 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us.

Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself.

it was uploaded already but I dont know where:

> $ sudo cat /var/crash/_usr_bin_gnome-shell.1000.uploaded

Lots of crashes on https://errors.ubuntu.com/user/a5880f5d67200136401b48e606e90173fb34300b11a89ca2507124cd0b5a044b7751eefba0fc9f16b27183bed1a11134c74d956b2b7161ee37aa1ee5d1d5c8ed

The one we are interested in is https://errors.ubuntu.com/oops/ad78e2e9-9344-11ee-8949-fa163ec8ca8c but I'm not able to access to its content.

[Daniel van Vugt (vanvugt)]

Thanks. Looks like we'll need to wait for it to happen again and hope there's a clean core dump in future:

js::DumpBacktrace(JSContext*, js::GenericPrinter&) () at /lib/x86_64-linux-gnu/libmozjs-115.so.0
js::DumpBacktrace(JSContext*, _IO_FILE*) () at /lib/x86_64-linux-gnu/libmozjs-115.so.0

I don't see any crashes in the top 100 gnome-shell crashes of 23.10 that would match that so please check to see if it's caused by a local extension. To do that please run:

  cd ~/.local/share/gnome-shell/
  rm -rf extensions

and then log in again.

[Pirouette Cacahuète (lissyx)]

The only extensions installed are:
> $ gnome-extensions list
> <email address hidden>
> <email address hidden>
> <email address hidden>
> <email address hidden>
> <email address hidden>

[Daniel van Vugt (vanvugt)]

Your config mentions b'enabled-extensions' b"['touchpad-indicator@orangeshirt', 'suspend-button@laserb', '<email address hidden>', 'cpufreq@konkor', '<email address hidden>', '<email address hidden>', '<email address hidden>', '<email address hidden>']"

But either way please follow the instructions in comment #9.
