[Bug 1714989] Re: gnome-shell crashed with SIGSEGV in g_type_check_instance_cast() from st_label_set_text() (dash-to-panel specific?)
I’m encountering a similar crash, this time in "g_type_check_instance_is_fundamentally_a", and not "g_type_check_instance_cast". Attached are the gdb.txt and journalctl.txt files generated following the procedure given above. This time it seems that it is coming from another extension, Pomodoro, that I’ve been using without any crash before upgrading to Ubuntu 17.10. So it looks like this regression could potentially affect other extensions. ** Attachment added: "gdb.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1714989/+attachment/4985108/+files/gdb.txt -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1714989 Title: gnome-shell crashed with SIGSEGV in g_type_check_instance_cast() from st_label_set_text() (dash-to-panel specific?)

Ok, actually that's not needed...

Paul, you need to do that from another system via SSH or from tty3 (or any free one), although you still might not be able to go back to the tty when frozen...

So this is mostly triggered by extensions (and considering how things are done, we can't prevent them). Or some wrong JS code which we didn't identified yet. Crash for users using dash-to-panel is fixed (I've proposed the fix upstream https://github.com/jderose9/dash-to-panel/pull/263), for the others, gjs_dumpstack's are welcome, or we need to wait some debugging bits to be there. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1714989 Title: gnome-shell crashed with SIGSEGV in g_type_check_instance_cast() from st_label_set_text() (dash-to-panel specific?)

Indeed these bugs might be triggered by one extension, more than vanilla experience, but they still underline issues in the code, so it's still a bug we've to fix. As I said, if you happen to catch this wile running gnome-shell in gdb, please run `call gjs_dumpstack()` from the gdb shell in order to get logs in your journal. Related to this, thanks Juerg. I've a point now, at least.

The dash to panel extension is not present on my system (Ubuntu GNOME), so the bug is surely not specific to that, as seen in the linked GNOME Bugzilla report.
