Application that crashed: kdevelop
Version of the application: 3.9.95 (using KDevPlatform 0.9.95)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-20-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
editing a large imported (autogen/make) project
kdevelop had worked for two days, suddenly crashes right after copy/paste of few lines of code, while editing

 -- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted
