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

I was using dolphin normally, when it crashed. Now, if I open dolphin, it displays normally, but hangs, and after a few seconds it dies. This is now happening every time dolphin opens, no matter what folder it is pointing at.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
