This looks very similar to a bug happening with me using newer cvs 
snapshots since approximately the same time. New projects will be set 
up but not be incorporated, and existing KDevelop 2.1.5 projects cannot 
be imported due to segmentation faults.

The last backtrace lines always look alike but I am not able to trace 
Gideon down to it as KDevelop 2.1.5 does not react to breakpoints 
and/or single stepping when I try to debug Gideon in there.

(Any ideas about this? Debugging other -- simple -- projects of mine 
does work.)

I am not sure whether this is a problem of Gideon or KLibs because I 
perceive quite a lot of segfault crashes more than before from other 
KDE apps as well since I upgraded to KDE 3.1.0 (most of them in 
Konqueror, by the way).

This Gideon crash is exactly reproduceable, however.

This is the most recent backtrace. Gideon crashed in this case when I 
tried to import a 2.1.5 project.

The segfault crash always occurs in 
 
#6  0x4101bff1 in QString::findRev(QChar, int, bool) const ()
   from /usr/lib/qt3/lib/libqt-mt.so.3

as well when I try to set up a new project.
