Trac RSS feed broken

For the past few days, trying to browse the RSS feed at

http://dev.rubyonrails.org/log/?limit=100&mode=stop_on_copy&format=rss

results in:

Python Traceback

Traceback (most recent call last):
  File "/opt/csw/lib/python2.3/site-packages/trac/web/main.py", line
406, in dispatch_request
    dispatcher.dispatch(req)

KeyError: 'author'

Some more broken stuff :

This started working again for a day or so, but then it stopped, so
I'm bumping this in case someone thought it was fixed.

I'm using the following URL which is working fine for me:

http://dev.rubyonrails.org/timeline?milestone=on&ticket=on&changeset=on&wiki=on&max=50&daysback=90&format=rss

Ah, interesting - that does seem to work. And it looks like the
<link> tag on the trac wiki has changed to that, so nobody else will
run into the problem either. So what am I saying? I'm saying let's
say no more about it!
