Revision logs with subrepositories

[Manuzhai]

The following traceback results from requesting r492:501 from my Trac repository:

Traceback (most recent call last):
  File "/usr/lib/python2.4/site-packages/trac/web/modpython_frontend.py", line 205, in handler
    dispatch_request(mpr.path_info, mpr, env)
  File "/usr/lib/python2.4/site-packages/trac/web/main.py", line 139, in dispatch_request
    dispatcher.dispatch(req)
  File "/usr/lib/python2.4/site-packages/trac/web/main.py", line 107, in dispatch
    resp = chosen_handler.process_request(req)
  File "/var/www/trac/trac/versioncontrol/web_ui/log.py", line 139, in process_request
    % (path, rev), 'Nonexistent path')
TracError: The file or directory '/' doesn't exist at revision 501 or at any previous revision.

My repository is at /var/svn/xm, but I've put my repository_dir as /var/svn/xm/joss. I didn't delete anything in between 492 and 501, so '/' is definitely there. (This happens with r2237.)

Looks like a duplicate of #1930.
