Application: kate (3.10.1)
KDE Platform Version: 4.10.1 (Compiled from sources)
Qt Version: 4.8.4
Operating System: Linux 3.8.3-gentoo-z1 x86_64
Distribution (Platform): Gentoo Packages

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

my indenter calls KateDocument::defStyleNum() w/ line number value set to -1 (yep, this was error in my script), but kate shouldn't crash anyway.

The crash can be reproduced every time.

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