impossible to access Timeline page when direct connection to this page

[stephane-thiers@…]

The timeline page adress is saved by my web browser so I directly access to Trac by the timeline page. But after connecting, any pages are accessible unless the timeline page (show a message explaining I must login to access the page). Sometimes, this message disapears after about 10 minutes. Today, the message is different (Oops page) and here is the Python Traceback.

Traceback (most recent call last):

Duplicate of #3831.

You should upgrade to 0.10.4 and fix the repository cache using TracAdmin's resync command.
