Application: kdevelop (4.4.1)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.8.0-26-generic x86_64
Distribution: Ubuntu 13.04

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

I was editing the main CMakeLists.txt file of a project that consists of multiple CMakeLists.txt files (subprojects). I was just removing some invalid text from the file right after opening it. Then I pressed Ctrl+S in order to save the changes and KDevelop crashed.

KDevelop managed to save the changes before it crashed.

I havent tried to reproduce this bug.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
