I just got a chance to re-run the test without a previous Buildbot  
version installed (just to be safe), and both 0.7.7 and 0.7.8 have  
the same test failure.

Since it doesn't seem to be a regression in Buildbot itself, I'm  
going to push 0.7.8 into Fink.

I would still be interested to know if anyone understands this test  
failure, or if they know that upgrading e.g. Twisted to a given  
version will fix this.
