I looked at the code - and it would seem that it is possible for the 
path passed to be uninitialised -
which would cause the crash.   I have hacked the XGFontManager.m code to 
ensure that path is initialised
to a reasonable value.

You could try again with the latest code from CVS.

However, the only way that I can see for the path to be uninitialised is 
if the GNUSTEP_USER_ROOT is not set,
which should not be happening as that should be set up by the standard 
GNUstep.sh script.
