I already know how XSetErrorHandler() works.  If you set an error handler, you
will steal errors from gdk.

You can attempt to work around it; XSetErrorHandler() will return the old error
handler, and you can call that if a particular error is not for your display,
but this is a problem a) if ximagesink is initialized before gdk (because gdk
will simply complain and abort instead of calling the ximagesink error handler)
or b) if you have multiple ximagesinks, and attempt to free them in a different
order than allocated.

It's not too bad if one sets an error handler, runs some operations, calls
XSync(), and then sets the old error handler.  But having an error handler set
all the time should be reserved for gdk, since gdk really needs it.
It's a problem in Xlib.  It sucks, I know.
