Re: crash: x_error_quitter

[Richard Stallman]

    This is Yet Another Unnecessary X Protocol Error Crash, probably the
    5th or 6th one to date.  As I've said many times, it's not necessary
    for Emacs to crash on X protocol errors, since they are not fatal
    errors, and can occur on misconfigured X servers.  The only reason to
    crash is to annoy the user.

The reason we make this crash is so we can find the causes and fix them.
