Timeline not showing - getting error

[Jordan]

We have a fully functioning SVN/Trac system, but one of our projects is not showing the Timeline and Browse Source data. Actually, the timeline does work, but you cannot view the checkins. So, something's out of sync between the svn and trac systems. I know it was working not that long ago, and haven't changed either svn or trac recently.

If we were just starting the project, I would just re-create the repo and the trac project, buuuut, we're now 6 months into the thing and I can't afford to loose the change lists. Plus, we have developers working on the project all day, so taking the time to pull everything down and rebuild would be costly. If there's any way you most excellent Trac gawds can help, I'd be very grateful 8-)

Here is the traceback:
