Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-17-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Well, I've never had much love for Konqueror. It hardly works most of the time but now it's just starting to crash whenever it hits any sites with moderately complex scripts. My system in general has been quite unstable lately, would anyone see anything else in back trace that could be causing this instability. Another major source of instability has been open office. I have never seen it so buggy in Windows or Gnome. There may be some compatibility issues that it's having with Plasma.

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
