Hello Richard,
thanks for the fast response.
I failed to tell you the -b0 means the current boot,
therefore if you rebooted with -b-1 might the boot that
contains the crash.
But maybe you could improve the output of coredumpctl
quite a bit.
Could you please add the debug symbol package repository
like in [1] and install these packages?
gdb libglib2.0-0-dbgsym gnome-shell-dbgsym libgjs0g-dbgsym
libmozjs-78-0-dbgsym libmutter-7-0-dbgsym
Then you could again invoke 'coredumpctl gdb 18825',
that should print mostly the same information but give
you a "(gdb)" prompt, where you could issue the command
'bt full' and forward this output again?
Kind regards,
Bernhard
