[Bug 338429] [NEW] Cache problem: "TypeError: previous_rev() takes exactly 2 arguments (3 given)"

[Adam Buchbinder]

Public bug reported:

Binary package hint: trac-git

I'm running trac and trac-git, with cached_repository = true. When I try
to view a revision, I get the following error (summarized):

While doing a GET operation on
`/changeset/afc71fcc75bd4287c5d8e41bb28f5bb39f476f8b`, Trac issued an
internal error.

Traceback (most recent call last):
  File "/usr/lib/python2.5/site-packages/trac/web/main.py", line 423, in _dispatch_request
    dispatcher.dispatch(req)
  File "/usr/lib/python2.5/site-packages/trac/web/main.py", line 197, in dispatch
    resp = chosen_handler.process_request(req)
  File "/usr/lib/python2.5/site-packages/trac/versioncontrol/web_ui/changeset.py", line 323, in process_request
    self._render_html(req, repos, chgset, restricted, xhr, data)
  File "/usr/lib/python2.5/site-packages/trac/versioncontrol/web_ui/changeset.py", line 406, in _render_html
    prev_rev = repos.previous_rev(chgset.rev)
  File "/usr/lib/python2.5/site-packages/trac/versioncontrol/cache.py", line 241, in previous_rev
    return self.repos.previous_rev(rev, path)
TypeError: previous_rev() takes exactly 2 arguments (3 given)

I'm running trac 0.11-2 and trac-git 0.0.20080710-1 on Ubuntu Intrepid.
