mutter#2570 was reported to Debian as <https://bugs.debian.org/1036268>.

The crash that Krassy Boykinov reported as #1010478 doesn't look like
mutter#2570 to me: the kernel message says the segfault was inside
libmutter, whereas in mutter#2570, the segfault seems to be inside
libwayland-server. We should try to keep to one bug per Debian bug number,
otherwise it becomes increasingly difficult to fix anything.

A backtrace from the crash would be very useful information for this or any
other crash. Please see <https://wiki.debian.org/HowToGetABacktrace>:
usually the easiest way is to use the systemd-coredump package, as described
in <https://wiki.debian.org/HowToGetABacktrace#Core_dump>.

Ryan: If you are experiencing a crash that closely resembles mutter#2570,
then that's in-scope for #1036268 but out-of-scope for #1010478.
Please see <https://bugs.debian.org/1036268> for more information,
including prerelease packages containing a backport of the upstream fix.
Or, if your backtrace does not resemble mutter#2570, please report it as a
separate bug.

Krassy Boykinov: Is this crash that you reported against gnome-shell/mutter
version 42 still happening in version 43.x? If not, we can close the bug.
If it's still happening, a backtrace would be very useful (we're unlikely
to be able to fix it without that information).

Thanks,
