Comment 3 for bug 493575

I have now duplicated this bug on ubuntu 8.04 with buildbot 0.7.6-1. I have copied the output from twistd.log below, and have attached the adjusted master.cfg file needed to reproduce this on hardy (the locking commands were removed as they are not understood on this old version)
