Bug 449845

Application: plasmashell (5.24.0)

Qt Version: 5.15.3
Frameworks Version: 5.90.0
Operating System: Linux 5.13.0-28-generic x86_64
Windowing System: X11
Distribution: KDE neon User - 5.24
DrKonqi: 5.24.0 [KCrashBackend]

-- Information about the crash:
I repeatedly see this same error (or very similar error) for at least 1 year and a half.
I've reported it at least 4 times.
I would like to learn enough to help debug and resolve this error, however, my knowledge of C++ and QT is insufficient at this time.

My KDE Neon now has the latest version of Plasma Desktop and KDE Framework and the bug keeps repeating. It's a little frustrating that I can't do anything else to be able to help in any way.

Is there any documentation somewhere that teaches how to interpret the traceback captured by drkonqi?
I can easily do this for Python tracebacks, but C++ + QT tracebacks is still a mystery to me.
