Bug 235595

Application: kdevelop (3.10.2 (using KDevPlatform 0.10.2))
KDE Platform Version: 4.4.2 (KDE 4.4.2) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.31-20-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
I got a crash after (accidentally) clicking the "Debug" button.

I see that bug 201030 looks similar, and is resolved "invalid" with a comment "your installation is somehow broken". I'm fairly certain that my KDevelop is installed correctly; I've run into problems earlier and fixed them by following the instructions at http://www.kdevelop.org/mediawiki/index.php/KDevelop_4/compiling (except that I installed KDevelop in /usr/local rather than $HOME/kdevelop4).


 -- Backtrace:
Application: KDevelop (kdevelop.bin), signal: Segmentation fault
The current source language is "auto; currently c".
