I'm afraid it has a locking issue again (though a more high-level one 
now): [1]

I guess this is due to the IRC backends exception being handled 
improperly (i.e. not returning the lock when an exception occurs).
The current upstream release seems to have the same problem (though it 
probably won't occur as the IRC module has been fixed):

buildbot/process/base.py:

If there's an exception in self.build_status.buildStarted(self), no 
further instruction will be executed and the build is locked forever.
IMO we should upgrade to 0.7.10 anyway, as it at least fixes the bugs 
triggering this behaviour. Also since it's a local installation (maybe 
even put into git) we could fix it on our own.
