Bug 307484

Application: dolphin (2.0)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-31-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

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

Reorganising files in a directory tree, moving from one folder to the more appropriate folders. 

- Unusual behavior I noticed:

Just before the crash, the files that I had moved before were visible in as a tree above and disconnected from the real filesystem tree, like what comment 7 in bug #294616 describes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
