Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
- 2 dolphin windows open.
- copied large file (600mb) to usb-stick.
- immediately after file-copy complete i 'safely removed'/unmounted the usb-stick via the default plasma-widget in the taskbar.
=> dolphin crashes.

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