[Buildbot-devel] exception after checkout in buildbot 0.3.4

[Timothee Besset]

I got the exception pasted below twice recently. Seems to happen after the
build bot has been up for a few days. The build slave is on the same
physical host, it's a vmware machine.

One thing I'm noticing, not sure it's relevant, is that the date on the
vmware machine seems to skew quite badly. It lags of about half an hour
within a few days. I'm gonna try to fix this in case it's related.
