When was your last Git compile before that?

The file etc/DEBUG describes how to start Emacs in the X synchronous
mode under a debugger (look for "X protocol errors").  Please invoke
Emacs as explained there, and then show the backtrace when the
breakpoint you set on the function x_error_quitter breaks.  This will
tell us which code causes these errors, and hopefully provide enough
hints to identify the reason of this.

Thanks.
