Application: kdevelop (4.0.1 (using KDevPlatform 1.0.1))
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.7.3
Operating System: Linux 2.6.39-1-686-pae i686
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
(1) Create a new source formatter (copy of Java, with tabs instead of spaces)
(2) Edit some code -> The new formatter is not functioning, spaces are still used instead of tabs
(2) Click on Settings (settings dialog opens)
(3) Click on Source Formatting -> Crash (segfault)

This happens independantly of whether there are projects loaded or not, and each time this settings module is clicked on.

Kdevelop now indents my code wrongly, I have to manually adjust each line. I'm also thankful for any workarounds (e.g. how to turn off automatic source formatting without accessing the settings module).

The crash can be reproduced every time.
