[Buildbot-devel] reconfig causes exceptions.KeyError: 'category'

[Russell Gallop]

I have just updated my build master to 0.8.3p1 from 0.8.2 (previously 
upgraded from 0.8.0) and reconfig will not work for me, even with no 
changes to pick up.

I get:
2011-01-18 12:05:09+0000 [-] configuration update started
2011-01-18 12:05:09+0000 [-] Unhandled Error

            if setup['category'] != self.category:
        exceptions.KeyError: 'category'

Never saw reconfiguration finish.

-I get this on two different buildbots that I run. One that makes use of 
categories and one that doesn't.
-I did buildbot upgrade-master after installing the new version and it 
didn't change anything in the master.cfg
-restart works okay

Any ideas? Could I be doing something wrong when upgrading?
