Intellij does not recognize the project structure for Ruby on Rails

Hello,

I'm trying to check out a project from GIT using IntelliJ.
IntelliJ reports that it can connect to the GIT repository without problems, and it actually checks out the files as well.

When I look at the files on disk, the file structure is correct and everything is there.
However, when I try to open the structure in intelliJ, this is what I get as output:

This is how the structure looks like in IntelliJ : http://i40.tinypic.com/6z5ym8.png
I have no idea why this is happening. My other projects on disk work fine, but when I check out something new or try to import something new into IntelliJ it totally fucks up.


Environment:

- Mac OS Lion
- RVM
- Rubies 1.8.7, 1.9.2 and 1.9.3

Reinstalling the plugin did not help
I'm not reinstalling IntelliJ !
