'a couple of months' is quite bad - and makes it quite difficult to narrow down
what could cause it now.

What openSUSE Version are you playing this on? (I'm just installing it again
and will try to reproduce - I'm using TUmbleweed)

Thanks for the detailed descriptions to reproduce it - that will surely help I
hope

That's the actual issue we need to narrow down. If you run this on a recent
version of openSUSE, systemd-crashhandler should have intercepted it and
produced a coredump.

You can cehck that with 'coredumpctl' - you should find ufoai there in the list
of crashed tasks. If so, you can do:

coredumpctl gdb PID
(replace PID with the number found in the earlier coredumpctl command)

at the (gdb) prompt, type "bt" (don't forget to hit enter)

gdb MIGHT be asking you to install -debuginfo packages; follow the instructions
given by gdb how to do it (you can copy the zypper command line produced) -
then reproduce above steps, until no further debuginfo is missing.

Then copy the output of "bt" in a text file and attach it here for review.
