java.lang.AssertionError: A stub in a non-stub file

Hi,

I have a rails 3.2.13 with ruby 2.0 project that I am working on.

Since the update to ruby 2.0 Rubymine is acting weird (no code completion, slow syntaxt higlight, go to definition does not work)

I've took a look into the console and there are a bunch of errors there:

Do you think this is causing the weid behaviours?
