Thanks.  However, when Emacs aborts in x_error_quitter, the backtrace
is usually not useful (due to asynchronous treatment of X errors).  So
please run Emacs in X synchronous mode and post the backtrace from
that session.  The file etc/DEBUG explains how to do this; search for
"If you encounter X protocol errors" there.
