You should be able to fix it yourself if you want; in retrace/glws_glx.cpp,
into init(void) add a call to XSetErrorHandler with a handler function (that
you'll need to write).  The handler function may be empty, as the
corresponding waffle patch does:
http://lists.freedesktop.org/archives/waffle/2012-November/000125.html

(but you can also print error messages with XGetErrorText).

See "man XSetErrorHandler" and "man XErrorEvent" for details.
