Application: kate (3.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.9.3-030903-generic x86_64
Distribution: Ubuntu 13.04

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

1) started Kate (tried commandline with 'kate', tried dolphin w/ 'open with->kate', tried session manager with new session, ...)

expected behavior:
- Kate starts

actual behavior:
- Kate immediately crashed (when using the session manager, Kate only crashed after selecting a session or 'new session')

note:
I have the ipython console and related plugins enabled which likely are responsible for the crash. Using Kate from git (pulled yesterday) works fine with the same configuration, just the backported 3.11.2 now dies on every startup.

The crash can be reproduced every time.

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