It depends on what you want to do.  If its likely to be a long debug session,
then I would say use Emacs.  It should be easier to see what is going on.  As
you just want a stack trace, then I would just run GDB from the command line.

Compiling with -g should be good enough.  I suggest following Jan's
instructions more carefully.  You said:

but thats because the breakpoint for x_error_quitter wasn't set:

If you start with "gdb emacs" you shouldn't get an error and the breakpoint
will be set.

Send the stack trace here, as Jan says.  It won't mean anything to me as I
know little about X and even less about Emacs 23, but someone else may
understand it.
