Bug 301355

Application: kate (3.8.3)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

I was editing PHP(HTML) mode, trying various combination of variables (remove trailing spaces, changing selection colors and some other).
Then I click to see the dialog to choose the associated mimetype, and kate crashes

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