Description Martin Koller 2013-02-07 20:37:03 UTC 
Application: konqueror (4.10.00)
KDE Platform Version: 4.10.00
Qt Version: 4.8.4
Operating System: Linux 3.4.11-2.16-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

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

I wanted to open this link

https://bugs.kde.org/buglist.cgi?bug_severity=crash&bug_status=UNCONFIRMED&bug_status=CONFIRMED&bug_status=ASSIGNED&bug_status=REOPENED&bug_status=RESOLVED&bug_status=NEEDSINFO&bug_status=VERIFIED&bug_status=CLOSED&chfield=%5BBug%20creation%5D&chfieldfrom=2013-01-01&chfieldto=2013-01-31&list_id=479548&query_format=advanced&order=bug_id&limit=0

which always crashes konqi when I have WebKit defined as the default engine. With KHTML there is no crash.

The crash can be reproduced every time.

Can't reproduce the crash using KDe built from git master
Comment 2 Martin Koller 2013-02-23 13:57:27 UTC 
I checked again and still have the crash but not directly when clicking the link but when reloading the page which shows the content of that link. Same backtrace.
