Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.95 (KDE 4.2.95 (KDE 4.3 RC1))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-11-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
crash happened after i cancelled the window to select which program i wanted to use. i had downloaded a pic from gmail.com with firefox. i double clicked inside the smaller download list window. 

the "choose program" window popped up. i hit cancell. then KDE crashed. my bash terminal stayed up. my firefox window stayed up.


this crash did not appear to be from an application. more like a general kde window.
