Bug 300814

Application: kded4 ($Id$)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.3.7-1.fc16.x86_64 x86_64

-- Information about the crash:
- Unusual behavior I noticed:

I occasionally use a Dell docking station with my Dell Precision notebook (FC 16, Scientific Spin).  When on the docking station errors occur when trying to access (presumably) mounted USB drives and mounted NTFS partitions through Dolphin.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
