Bug 297832

Application: dolphin (2.0)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
While working on KDE Partition Manager I deleted a partition from a memory stick (the file system obviously was not mounted, but I _think_  it had been mounted previously) and Dophin (which had been sitting in the background) crashed with this backtrace.

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