I'm using the latest CVS as of this morning.  Are you working with a recent 
build? 

I'm using QT 3.1.2 form my own build, and I'm running my own build of KDE 
3.1.1 which came from running konstruct.  I built Gideon against a CVS HEAD 
of KDE.  I'm currently rebuilding the kdelibs from the 3.1.1 tarball because 
I'm getting the wonderful "checking if UIC has KDE plugins available..." 
error.  

If you're wondering why I have 3 kde3 builds, and two QT builds, it's because 
there seems to be a problem with the SuSE QT 3.1.2 rpm which breaks my fonts. 
And, well, that means the SuSE KDE 3.1.1 won't support my builds because I'm 
using a different QT than they provided.  I already had the KDE from CVS, so 
I built Gideon against that.  For a while that had been working. But now...

I just started Gideon, created a C++ KDE Application Framework project, 
clicked the new class icon, put in the name of the class, and submitted the 
form.  It crashed immediately with this backtrace:
