I'm not using systemd so I don't think this will be an option. However, I think
I could still use the gcore command-line utility to generate a core dump (or
attach GDB to the crashed process and use the gcore command).

...if it triggers. Because I haven't seen it lately. I also tried logging in
and out again (+ killall -u username -9) multiple times, but I couldn't
reproduce it.

I'll make sure to investigate for any other signs such if it reoccurs.

Do you have any references to similar bug reports? Do you think it is a drkonqi
issue or rather a Qt issue (e.g. perhaps something similar to QTBUG-39285)?
