OK then lets try again :-)

What I was trying to suggest here is to start you application in debug
mode, that is you need to have gdb installed and then do:

openapp --debug ./GSTest.app (or what ever application you want)
as soon as gdb starts up you type in:

b XGErrorHandler

This will tell you that it cannot find this function, which is fine at
that time, so you type in "y" and start the application by pressing "r"
or "run". Next your error should be happening and gdb should end up in
the GNUstep error handler for X. It stops there and you should type in
"bt" or "backtrace" to get more information on what caused the problem.
you may have to press return once or twice to get full error information.

Please send me this back trace and if need be, I will explain the other
debug step in a follow up mail.

Cheers,
Fred
