Application crashes if a folder dropped on application

[lfekson]

If application doesn't define anything for drag and drop, then dropping a folder onto any piece of the application (that user can do occasionally) causes application crash. In development mode after crash the application screen is replaced with error message:
Failed to compile /Users/someuser/foldername: Can't stat /Users/someuser/foldername
Error: Can't stat /Users/someuser/foldername

Absolutely the same crash happens if application uses drag&drap, but user dropped a folder outside of the defined drop zone.
