gnome-shell crashed with SIGTRAP in ObjectInstance::disassociate_js_gobject() from std::function<void (ObjectInstance*)>::operator() from ObjectInstance::remove_wrapped_gobjects_if() from ObjectInstance::update_heap_wrapper_weak_pointers

This crash has the same stack trace characteristics as bug #1841794. However, the latter was already fixed in an earlier package version than the one in this report. This might be a regression or because the problem is in a dependent package.

StacktraceTop:

It doesn't really look the same as bug 1841794 so ignore comment #2. This does however look like a pure gjs/mozjs bug.

It appears you have a number of non-Ubuntu extensions installed:

'<email address hidden>'
'<email address hidden>'
'<email address hidden>'
'<email address hidden>'
'<email address hidden>'
'<email address hidden>'
'<email address hidden>'
'<email address hidden>'
'<email address hidden>'
'<email address hidden>'
'<email address hidden>'
'desktop-icons@csoriano'

Since we find so many bugs are caused by extensions we ask that you uninstall ALL of them (don't just disable them) and then tell us if the problem reoccurs.

Nevermind. Confirmed the same crash is affecting Ubuntu 19.10 too:
https://errors.ubuntu.com/problem/c81c4bee503e4c7ae8551cb68187b7da66472c9b

It appears this crash is probably caused by one or more buggy extensions. It seems to practically never happens for most people using 20.04.

So please try removing some or all extensions to figure out which is to blame.

Is it normal for extensions to be able to crash native gnome/Ubuntu processes? Seems strange to me.

I mean, it doesn't sound logical for me for the error tracking system to not be able to distinguish between issues with extensions and ones with core gnome. But i don't know about gnome enough.

This has not happened since I've installed the latest version. Please close
the bug. As far as I'm concerned it would appear to be fixed even if you
are not aware.
Thanks.

The error tracker link for this bug suggests it isn't happening at all in 20.04 with 3.36:

https://errors.ubuntu.com/problem/c81c4bee503e4c7ae8551cb68187b7da66472c9b

Maybe we just need a new link?

Thanks!
