I'm not so sure right now (should look at the gdkx.[ch] code to find out) but I think
that gdk makes a call to `abort()' when encountering errors from the X server.
(I'm very not sure about that; guess guess).

What I usualy do with theese errors is just fix the problem. Your problem is that you are
attempting to access a private X resource and you dont have the privilages required (maybe
you need to run the program as the user who started the server ?).

just another thought; is it possible that `gdk_x11_get_default_root_xwindow()' is
returning something like '0' or '-1' ? (some kind of error code to say that it
couldn't find any default xwindow ?); and maybe '0' is some super private implicit
resource ID ?, like I said, just a thought.
