Consider this fixed [1]. Resubmit your failed build-jobs for Extras
and EPEL and see.

After I'd noticed that approx. 5 out of 6 noarch build-jobs on the
ppc2 server failed with the same symptoms, I've picked yum-cron as a
test pkg for an online-debugging session on the ppc2 host. As another
pkg that had failed very often, I've tested the final patch with
ctapi-common.

The reason for failure was a race condition between plague 0.4.4.1 and
mock. The plague builder did not monitor the mock state accurately
enough. Mock could change its state (e.g. from prepping/setup to
building) while the plague builder was sleeping. In the cases I've
observed, mock had exited already when plague woke up and made a wrong
assumption about the state mock was in when it exited.
