Bug 298939

Application: kate (3.8.2)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was experimenting with multiple sessions, configuring build plugin in one, and sql plugin in another. I was swapping back and forth just to inspect changes when it crashed on one of the session changes.

Sorry I dont have debug symbols, system is on an 8gig ssd. When I get I a moment, I'll see where those get installed and setup a subvolume to install them on for a more useful addition to this if it happens again.

The crash can be reproduced some of the time.

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