Error importing / opening Composite project

I thought the May 18th nightly build may have resolved this issue but apparently it hasn't.  I'm getting this error message when trying to import a project.  Any ideas as to why this might be happening?

I thought it might be related to this but we don't have any REST elements in our project.
