Bug Description

The code in which the above error occurs is in buildbot 0.7.9. The same code does appear in later versions, but there have been changes to the module (and elsewhere, naturally) so it's worth upgrading to see if this problem goes away or if the root cause manifests itself in a different way. Currently we're close to running 0.7.11p3.
