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

1. Open kdevelop (you can create a new project, but not obligatory)
2. Add any file (or edit an existing one)
3. Add some lines (if new file)
4. Set the bookmark as you like
5. Try to delete all bookmarks

It also present on a newly created user - no old saves in kdevelop configuration.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
