Application: kdevelop (4.2.60)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.1
Operating System: Linux 2.6.38-3-generic x86_64
Distribution: Ubuntu natty (development branch)

-- Information about the crash:
KDevelop will segfault with some files when creating a new line or sometimes when adding brackets. Removing all settings to defaults does not seem to help the problem. Language being used is Unigine Script which is almost the same as C++ but not quite.  4.1 and earlier did not exhibit this behaviour.

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