AssertionError: Trying to enable TracGit

[admin]

How to Reproduce

While doing a GET operation on /admin/general/plugin, Trac issued an internal error.

I have been trying to install the Trac-Git plugin, but kept coming up with the "Can't synchronize with the repository (Unsupported version control system "git". Check that the Python support libraries for "git" are correctly installed.) error. I had run apt-get install trac-git on ubuntu 8.10 amd64. also run python easy_install against the setup.py of tracgit 0.11 i have also attached my trac project."

Request parameters:

{'cat_id': u'general', 'panel_id': u'plugin', 'path_info': None}
