Redmine

Whenever I try to browse a Subversion repository, by either http:// or file:///, the page throws a 500 error, and the log file gives me this:

ActionView::TemplateError (undefined method `length' for #<Enumerable::Enumerator
:0xb7221714>) on line #22 of repositories/_dir_list_content.rhtml:

Rendering /opt/redmine/public/500.html (500 Internal Server Error)

I'm no expert, but I don't think it's supposed to do that. The machine is running Debian 5. I tried both http:// and file:/// methods to access the repository. I'm certain that Redmine has sufficient credentials to read the repository.
