Redmine

I have install the redmine 2.0.3 and git on Centos server.

The redmine directory and the git repositories directory's owner is apache.

If I create a project on the git, the redmine can find the file and change history of it.

But when i click the "diff" button , the redmine give a internal error.

From the production.log , I got the following messages:

Started GET "/projects/demo/repository/diff?utf8=%E2%9C%93&rev=f3006a03cecb45aca98fd078d756c6c820b04143&rev_to=93be2a01746370837ab21b529872af4cf59af5f4" for 192.168.255.3 at Sat Jul 14 21:54:25 +0800 2012
