Error when forcing build through IRC

[lotodore]

After updating to 0.8.5, I got an error when forcing a build through IRC. The error looks like this on IRC:

[22:29:58] <Lotodore> build: force build proj [22:29:58] <build> Something bad happened (see logs): <type 'exceptions.AttributeError?'>

The twistd log file shows an error like this:  http://pastebin.com/48RPbbV1

A workaround, as explained by djmitche on IRC, is to change the line which causes the error (buildbot/status/words.py, line 524, in command_FORCE) to d = bc.submitBuildRequest(ss, reason) (i.e. deleting the props= from that line).

Logfile in the pastebin is
