Redmine

hi

when running redmine in the debugger, I get a lot of errors like this:

Exception `NameError' at /usr/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:443 - uninitialized constant Subversion

this has been happening before I started working on RM so I can't say its something I've broken. this is in Redmine 1.1, upgraded from 0.9.4.

Does anyone have an idea why this error is thrown so many times, and is it an error in the upgrade procedure or in RM 1.1?
