Have you tried upgrading to an actual release of Trac, such as 0.11.3, instead of using a 20 month old development snapshot?

[Christian Boos]

Right, please upgrade. We have plenty good 0.11.x released versions and a few release candidates as well available in TracDownload, all better than this old development version ;-)
