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

I was trying to navigate the file system in dolphin after executing it from konsole. At the Konsole prompt logged in as root in the Konsole I typed dolphin. Dolphin opened. I was able to navigate to folder depths in the tree when it crashed.

The crash can be reproduced every time.
