New description:

 I upgraded von 0.8.9 to 0.8.10 and now have this for every slave status
 display:

 {{{
 web.Server Traceback (most recent call last):

 packages/twisted/internet/defer.py:139 in maybeDeferred

 390            if allowed or path_always_viewable(request):
 391                return defer.maybeDeferred(lambda:
 self.content(request, ctx))
 392            else:

 118        except ValueError:

 }}}

 This happened for buildbots not even running. I did do upgrade-master once
 I noticed, so that ought to be not an issue. I also deleted all historical
 builds. Will it help to drop the sqlite database?
