I suggest to run Emacs under GDB in X synchronous mode, and then
examining the X error that brings it down.  The file etc/DEBUG
explains how to run Emacs in X synchronous mode, search for "If you
encounter X protocol errors".  We need to know the exact X protocol
request that caused the error, and also the backtrace from there.  The
GDB command "bt" will show the backtrace.

Thanks.
