Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-20-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I was copying files with Dolphin between two parts of the Dolphin window while other files were already copied. The folders were Samba-mounted. Dolphin asked for overwrite. When I chose "overwrite all" Dolphin crashed.
