If this is the upstream bug that looks similar, then it should have been fixed in libmutter-11-0 version 43.1-1. There have also been lcms-related crash fixes in liblcms2-2 version 2.14-1, and in libmutter-11-0 version 43.3-4. Please check whether this crash is still reproducible with the versions available in bookworm. If you still see this crash, please try to get a backtrace so that it can be solved.

Bug#1023013:
Dear maintainer, I encountered the same problem. Here is the problem in syslog (similar to what Bernhard Übelacker reported). The bug is only triggered by a few data-projectors. I'll try to post a backtrace ASAP.

Bug#1023013: gnome-shell: Segfault in liblcms2.so when plugging in HDMI, Wayland display
Dear Maintainer,
following is what I was able to extract from the dmesg lines
and the dbgsym packages.
It looks like it crashes in cmsSetHeaderRenderingIntent because
it was given a NULL pointer in parameter hProfile.
That's still not much information, but for this function name
an upstream bug shows up that might be related.
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/5875
Kind regards,
Bernhard

Can you get a backtrace from this crash? The information in dmesg is not usually enough to decide which package has a bug, and is very rarely enough to find the root cause and fix it. The easiest way is usually to install systemd-coredump. See https://wiki.debian.org/HowToGetABacktrace and more specifically https://wiki.debian.org/HowToGetABacktrace#Core_dump for details.

Bug#1023013: gnome-shell: Segfault in liblcms2.so when plugging in HDMI, Wayland display
Package: gnome-shell Version: 43.0-2 Severity: important X-Debbugs-Cc: twe...@debian.org On Wayland, when plugging in HDMI wire, GNOME shell falls into a segfault- restart-segfault loop, rendering it useless. Reproducible when unloading all shell plugins. Not reproducible when falling back to JWM on an X.org display. Problem seems to be related to liblcms2.so from package liblcms2-2, a color management engine known as LittleCMS. Hardware information: Lenovo ThinkPad P15v (Gen 1 from 2020), with Intel UHD Graphics and discrete nVidia Quadro P620. Software information: Kernel 5.19.0-2 from Main repository. Loaded TOMOYO instead of AppArmor as a security measure.
