Version:           3.0.0 (using KDE KDE 3.2.0)
Installed from:    Compiled From Sources
Compiler:          gcc-3.2.3 
OS:          Linux

I haven't compiled KDE and QT with debugging information. I have compiled the latest kdevelop CVS which exhibits the same behavior as the 3.0 version installed with gentoo.

Here is the stack trace:
