Description ren 2009-12-20 01:55:39 UTC 
Application that crashed: konqueror
Version of the application: 4.3.4 (KDE 4.3.4)
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-16-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I had a tab displaying a .png image, and I closed it with Ctrl-W, which caused a crash.

My previous actiion was closing another tab the same way.

 -- Backtrace:
Application: Konqueror (kdeinit4), signal: Segmentation fault
The current source language is "auto; currently c".

Comment 1 Dario Andres 2009-12-31 16:02:21 UTC 
- Have you tried to repeat the situation to check if Konqueror crash again ? Thanks
Comment 2 ren 2009-12-31 17:16:28 UTC 
After the crash, I re-opened Konq and had it restore my tabs, which included the one I had tried to close. I then closed the tab successfully.

I open image tabs fairly often, including .pngs sometimes, and usually closing them does not trigger a crash. I think it has happened to me once before in about a month of using Kubuntu 9.10.

Unfortunately it is hard to reproduce a bug that only occurs occasionally without a concrete steps on how to make it crash. If the problem perists in a more recent version of KDE, v4.7 and higher, feel free to reopen this ticket. Thanks for the report.
