Description Alex Richardson 2011-10-13 14:18:57 UTC

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:

Comment 1 Raphael Kubo da Costa 2012-04-03 12:14:53 UTC

This looks like a problem in kwebkitpart itself, similarly to bug 287567. Are you still able to reproduce this crash?

Comment 2 Dawit Alemayehu 2012-04-03 19:32:35 UTC

*** Bug 287567 has been marked as a duplicate of this bug. ***

Comment 3 Dawit Alemayehu 2012-04-03 19:36:58 UTC

This is something that has already been fixed in the latest stable version of kwebkitpart, v1.2.0. The function where the crash is happening does not even exist anymore.
