Bug 57451

Version:           3.0a4a (using KDE KDE 3.1.1)
Installed from:    Debian stable Packages
Compiler:          gcc-3.2 
OS:          Linux

I have imported a GTK+ C project successfully. (ran make/conf/exec in it)
then I tried to close the project (with some open source windows, but with the program itself not running), which reslted in SIGSEGV.
Here's the backtrace:
