Comment 12 for bug 972475

Nautilus now says "Scribus Document (application/vnd.scribus)" - this is after I assigned the file type to it permanently when I first tried to open it unsuccesfully.

Since Scribus is often mentioned as one of the major desktop applications in the Ubuntu official documentation, I was expecting a better user experience for this, much like when I try to open media files in unexpected non-free formats. See:

COuld we use the same mechanism to recognize Scribus files?
