This information is not enough to diagnose a root cause. Please could you
get a backtrace for the crash? Usually the easiest way to achieve this is
to use systemd-coredump: see
<https://wiki.debian.org/HowToGetABacktrace#Core_dump> and
<https://wiki.debian.org/HowToGetABacktrace#Running_gdb>.

It is helpful if you can use the reportbug tool to report bugs: that would
provide information on all the packages that gnome-shell depends on.

Thanks,
