Files in the StreamingAssets folder should not be imported

In the attached example project, an ogg file is included. The Editor imports this file. This shouldn't happen as :

1) Files in the StreamingAssets folder are copied as is, import process is not needed.
2) Importing takes time and therefore it makes it worse, if it's not actually used for anything
3) It will create files in the Library folder (and Cache Server?) that shouldn't be there.
