-- Information about the crash:
- What I was doing when the application crashed:
Connected an external hard disk
Mounted it through Dolphin file manager
Split the view (in Dolphin) and reached the desired destination in the 2nd view
Dragged the folder from the 1st view to the 2nd view and chose 'Copy here' when prompted

The crash can be reproduced some of the time.

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