In fact, the  GLib-GObject-WARNING message is due to libgnome bug which 
just have been fixed a few days ago. It should appear in the 
maintanence releases of 2.2 and in 2.4 of libgnome. See this page for 
the details: http://bugzilla.gnome.org/show_bug.cgi?id=109407

This message shows up on most systems and does not indicate the improper
behavior of gramps, python, pygtk, or pygnome, since the bug is in the 
gnome library itself (although it surfaces only in the bindings :-)

I have no idea why segmentation fault happens. I only know that is not 
necessarily related to the previous error message :-), since I have the 
one and not the other. 

To find out what causes the segfault, one can try inserting print 
statements into the code to determine how far the program goes and what 
exactly statement causes the segfault. A proper place would be the 
method __init__() of class Gramps in file src/gramps_main.py -- putting
   print "1"
   print "2"
and so on every so often should produce the output when this modified 
version is run, up until the segfault. After that, one can further split 
the block in question until the culprit is found. The important 
thing here is to run a modified version, not the one you have unstalled 
under /usr/local/bin or elsewhere. One can just do
   $ cd gramps2/src
   $ ./gramps.py
to run without re-installing every time. 

What to do after the culprit is found really depends on what it is. 
Unfortunately, it has to be done on SuSe machine and I don't have one. 
Richard, could you maybe try to pinpoint the segfaulting statement when 
you have a chance?
