Bug 311944

Application: kate (3.9.90)
KDE Platform Version: 4.9.90
Qt Version: 4.8.3
Operating System: Linux 3.7.0-7-generic x86_64
Distribution: Ubuntu Raring Ringtail (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I had a few files open, so I created a new session via the menu. After which I used the session quick open option to open a different session. I tried to reproduce this by re-opening kate and doing session quick opens between my two sessions, but it did not reproduce. I also tried to reproduce it by opening a few files and creating a new session before performing the session quick open, but it did not reproduce the crash.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
