Bug 260835

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.5.85 (4.6 Beta2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Nepomuk crashed on umount of an external storage device via dolphin.

-Additional issue perhaps linked or an other bug?: All partitions on external storage devices are shown twice in the device manager and dolphin.

-- Backtrace:
Application: Nepomuk-Dienst (nepomukservicestub), signal: Segmentation fault
