Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64

What I was doing when the application crashed:
Dolphin crashed after unmounting a usb stick after copying files to it.  If i unmount as soon as the copy finishes dolphin crashes, however if i wait 30 seconds after copy complete it does not crash,
