Can you reproduce this crash at will? Does it happen to more than one file?

No, sorry, it was the first and only crash, and when DrKonqi came out I 
reported it.

ark (2.15) on KDE Platform 4.5.00 (KDE 4.5.0) using Qt 4.6.3

- What I was doing when the application crashed:
Extracting a tar.gz archive directly opened from Konqueror (without saving it). Ark crashed on quitting automatically after extracting. The extraction has completed successfully (all files have been extracted).

I have experienced the same crash once before but also multiple times where it didn't crash (with the same settings). Seems a bit strange ...

Comment 8 Raphael Kubo da Costa 2010-08-15 01:10:07 UTC 
SVN commit 1163720 by rkcosta:

Remove the finished() slot reimplementation.

It called unregisterJob() and did many things it also did.
unregisterJob() calls resetUi(), finished() calls it after 1.5 seconds.

Since the default registerJob() implementation already connects a KJob's
finished() signal to the unregisterJob() slot, there's little sense in
keeping this duplicated code.

I'm still unable to reproduce this crash, but I think the above commits might help prevent it from happening.

ark (2.15) on KDE Platform 4.5.00 (KDE 4.5.0) using Qt 4.7.0

System is Kubuntu 10.04 LTS, I encounter problems with Ark very often recently, when dealing with rar archives. I've suspected problems with the rar unpacker and switched to non-free implementation, but the problems persist.
