Application: kontact (4.8.5)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-38-generic x86_64
Distribution: Trisquel 6.0

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

I booted gnulinux distribution trisquel 6.0 and started Kontact. The application crashes when I click on menu 'Configure Kontact'.
The problem appeard after 2-3 days after installation of trisquel and when some configurations in Kontact are made. These componets are active: Summary, Contacts, Calendar, To-do List. I does not matter which componet is active, when click on menu 'Configure Kontact'. No changes are made in deactivated components such as Mail etc.

The crash can be reproduced every time.
