How to Reproduce

While doing a GET operation on /timeline, Trac issued an internal error.

I was attempting to setup GitPlugin, and had successfully synchronized the repository using trac-admin.

[~/radio] zack@server1$ (git::master) trac-admin /var/lib/trac/ repository resync "radio" Resyncing repository history for radio… 26 revisions cached.2b63d275d1e16bbef08353] Done.
