Application that crashed: kget
Version of the application: 2.2.90
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2)) "release 138"
Qt Version: 4.5.1
Operating System: Linux 2.6.25.20-0.1-default i686

What I was doing when the application crashed:
Sometimes KGet crashes when clicking a download that has not been started (due to the group limit on number of downloads). 

First case: Right after adding a download, a click (r/l cant remember) on the stopped download crashed KGet. In another case a right click caused the context menu to show. Clicking outside this menu caused KGet to crash. In yet another case it took several clicks (and an opening+closing of the settings) before a final click made KGet crash.

 -- Backtrace:
Application: KGet (kget), signal: Segmentation fault
