Bug 285952

Application: kate (3.7.2)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Opening a C++ header file to begin work on, I had opened this file previously and worked with it inside kate many times, its just now choosing to crash when I attempt to select the file from the file browser.

The crash can be reproduced every time.

-- Backtrace:
Application: Kate (kate), signal: Aborted
