Description Pete Brown 2009-06-19 02:10:17 UTC 
Application that crashed: konqueror
Version of the application: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2))
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2))
Qt Version: 4.5.1
Operating System: Linux 2.6.28-13-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I have webkit enabled as the default view for html.
I was looking at gmail (which was vaguelly working but not completely but thats another issue).
I closed the tab and konqueror crashed. so i restarted the application via the crash dialog and restored the session and tried closing the tab again but i got the same crash.

Hope this helps.

Let me know if you need more information or testing.
:)

Hi guys,
It's been a while since i reported this and i have upgraded kde since then.
I am now running 4.3.1.
I decided to set my default view mode to qtwebkit again and loaded up gmail.
The good news is that it didn't crash my konqueror when i closed the tab.

I will keep using qtwebkit and see if have any other issues and will report them if i do.
Comment 3 Pete Brown 2009-09-22 02:35:28 UTC 
Looks like i spoke too soon.
Just after i reported this Konquoror started crashing whenever i closed a tab.
I am reinstalling the debugging symbols and will add the crash report to this bug.
