Application: kdevelop (4.6.0)
KDE Platform Version: 4.12.1
Qt Version: 4.8.6
Operating System: Linux 3.11.0-15-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
I was playing with working set (deleting them, creating them). Then I closed KDevelop. I reopened it to see working set opened by default, then I closed it once more, and it crashed.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
