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

I clicked create new, and typed an ftp filename. I always get 405 login OK (failed), but most of the time Dolphin also crashes when doing this.

The crash can be reproduced sometimes.

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