I think that the problem is because the Trac 0.12 have several SVN repositories.

I have the same problem, here is the backtrace:

File "/usr/lib/python2.4/site-packages/trac/web/", line 511, in _dispatch_request
File "/usr/lib/python2.4/site-packages/trac/web/", line 237, in dispatch
  resp = chosen_handler.process_request(req)
File "build/bdist.linux-x86_64/egg/revtree/", line 246, in process_request
  return self._process_revtree(req)
File "build/bdist.linux-x86_64/egg/revtree/", line 295, in _process_revtree
  youngest = int(tracrepos.get_youngest_rev())

and here the relevant code snippet

292	 def _process_revtree(self, req):
293	"""Handle revtree generation requests"""
294	tracrepos = self.env.get_repository()
295	youngest = int(tracrepos.get_youngest_rev())

It looks like self.env.get_repository() does not return anything, probably as the original reporter said because multiple repositories are supported. This is from a 0.12.2 trac with the svn checkout of the 0.12 branch of the revtree plugin.

self.env.get_repository() does report repository_dir from trac.ini This variable is not set on a default installation, setting the value with full path prevents return of NULL when using self.env.get_repository() On the other hand, setting this value will break multi-repo support
