Application: dolphin (2.2)
KDE Platform Version: 4.10.1
Qt Version: 4.8.2
Operating System: Linux 3.2.0-39-generic x86_64
Distribution: Ubuntu 12.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was filtering a partially open tree view using a three letter. Since the folder was restored from trash it wasn't visible and I deleted the letter for a fresh start of the filter, but the prog crashed.
- Custom settings of the application:
I had strange behavire with libreoffice. After installation of an extension the libreoffice refused to start - without trowing errors. Maybe the system was upset.

The crash can be reproduced sometimes.

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