Bug 283924

Application: ark (2.17)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.1.0-rc7-3-desktop x86_64
Distribution: "openSUSE 12.1 Beta 1 (x86_64)"

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

I was viewing a file inside the archive with the kwebkitpart. When I closed the ark main window (kwebkitpart still open) I got this crash. When I close the kwebkitpart before closing ark no crash occurrs. This is always reproduceable with every archive I tried.

The crash can be reproduced every time.

-- Backtrace:
Application: Ark (ark), signal: Segmentation fault
