I opened the latest RubyMine build and got the following error dialog as it was parsing a Rails project directory of mine:
"It seems that you have corrupted stubs in your RubyMine or Ruby plugin installation. Please reinstall!"
I am not aware of any problems with the Ruby or Ruby plugins in the project, though I do have a symlink for the vendor directory rather than a real directory.
This is a pretty fresh install--though I had a previous RubyMine installation, I removed the RubyMine-related files and folders in my Application Support directory. What else do I have to do to clean things up?
