Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-17-generic x86_64

What I was doing when the application crashed:
I stopped the job via the plasma/system tray notifier object and after that a popup appeared asking me to confirm overwriting a file. I pressed "Cancel" and Dolphin crashed. 

 -- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
