Maestro fails to start on OpenSuse 10.3 and Fedora 8. What can I do?

Maestro can fail at startup with the following error:

maestro: xcb_xlib.c:42: xcb_xlib_lock: Assertion `!c->xlib.lock' failed.
Maestro received ABRT signal.

The workaround on OpenSuse 10.3 is to set the following environment variable to a null value:

bash/ksh: export LIBXCB_ALLOW_SLOPPY_LOCK=""
csh/tcsh: setenv LIBXCB_ALLOW_SLOPPY_LOCK ""

There is no workaround on Fedora 8.

We thank Dow Hurst of the University of North Carolina, Greensboro, for this solution.
