Application that crashed: dolphin
Version of the application: 1.3

Qt Version: 4.5.1
Operating System: Linux 2.6.28-13-generic i686

What I was doing when the application crashed:
While I was copying between two USB external harddrives everything works fine. Then I wanted to copy another file from my "normal" harddrive to one USB-drive... then dolphin crashed. :-(
