Redmine

My organization uses darcs for all of our revision control and development, so I'm trying to get darcs set up as a repository in redmine. I'm having a couple of problems. I've set up a project and added a darcs repository to the project (using the local path to the repo). The first problem is that when I click on the "Repository" tab under the project, I get an error saying "The entry or revision was not found in the repository." The debug logs then show an internal server error as shown in the attached log file.

The activity tab does show all of my patches. But if I click on one of the patches and then click on one of the files that is in the patch set, I get the same error as above. Any ideas what the problem is?

I am using redmine-0.9.2 (from Gentoo linux's ebuild) as well as:
Linux version 2.6.31-gentoo-r6
