TypeError: list indices must be integers

How to Reproduce

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

The error occurs everytime I try to get access to the repository, e.g. when clicking on a changeset in the timeline or browing sources. It is not possible to use the browser at all.

Request parameters:

{'path': '/'}
