Bug Description

Launchpad's buildbot in build 40 showed the following failure. The failure cannot be reproduced there or elsewhere for the same revision, and so appears to be a spurious and intermittent failure. The test is being disabled for now, per policy.

A subsequent buildbot run (43) had the following failure. I am now disabling the entire doctest.
