Bug 240455

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.81 (KDE 4.4.81 (KDE 4.5 >= 20100527)) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.33-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I had Dolphin open, viewing a memory stick.  I told Dolphin to remove the device, and then closed Dolphin.  Then Plasma crashed.  I couldn't get it to crash again by repeating the steps, though.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
