Redmine

Im pretty new to redmine and ruby so I'm a little bit helpless in this. There are many very similar problems in the forums and bugtickets but none of them solved it for me.

The problem:
When I browse my git repository within redmine the request takes quite a long time and results in a Internal Server error. The production.log says:

Processing RepositoriesController#show (for [::1]:57835 at 2010-05-22 09:04:30) [GET]
Parameters: {"action"=>"show", "id"=>"myProject", "controller"=>"repositories"}

Done so far:

- Users can be retrieved from git
