Application: ark (2.17)
KDE Platform Version: 4.7.3 (4.7.3) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 3.0.6-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:

I used kark to open a zip file with an embedded htm file.  After reading that htm file, I closed the html window. Then I closed kark.  And I got this crash.

While I've tagged a possible similar one, the other report said that if they closed the khtml window first it didn't crash, whereas I do close that window first and still get the crash.

The crash can be reproduced every time.
