Description Leandro Santiago da Silva 2011-11-24 18:27:49 UTC 
Application: kdevelop (4.2.60)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-13-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
After fetching the code from master branch today (24th nov), Kdevelop started to crash everytime I open an existing file (via project tree or the quick open form).

I also removed the .kdevducain and .kde/(...)/sessions directories, but the result was the same.

The crash can be reproduced every time.

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

Comment 1 Milian Wolff 2011-11-24 18:49:53 UTC 
please remove the indent plugin, it was renamed to externalscript. the old plugin is ABI incompatible and triggers this crash.
Comment 2 Leandro Santiago da Silva 2011-11-24 19:00:44 UTC 
Yes, that resolved my problem. I just removed kdevindent.so and kdevindent.desktop from lib/kde4 and share directories.

Thx.
