When I looked through drkonqi-coredump-gui (in order to locate what would become the content of bugzilla.redhat.com/show_bug.cgi?id=2323199#c24), I saw:

Due to the lack of information there, I didn’t expect it to be useful. However, I did manage to acquire a trace:

Considering that bugs.kde.org/enter_bug.cgi states:
If you’re not sure this is actually a bug, instead post about it at https://discuss.kde.org.
If you’re reporting a crash, attach a backtrace with debug symbols; see Guidelines and HOWTOs/Debugging/How to create useful crash reports - KDE Community Wiki.
…and contains a generally mandatory reproduction section:
STEPS TO REPRODUCE

EXPECTED RESULT
…and:
- The trace I’ve acquired does contain a few
??s - I have no idea what caused it
…is it useful, at all?
