Does not seem to be fixed. I've just updated to
beaker-client-0.7.0-1.el6eso.noarch and the traceback appeared
again:

Sorry the rpos have not been updated

Petr, the beaker-stage repo has been rebuilt to include the latest code. Sorry for the delay

Verified with beaker-client-0.7.0-1.git.43.5c97321.el6eso.noarch.
Trace back no more present. Thanks for the fix.

Beaker 0.7.1 has been released.
