Public bug reported:

OS: Ubuntu 14.10
OpenLP: trunk

I have song database upgraded from V2.0.4 to V2.1.2.
There is an Author called "Author unknown" for songs I do not know the author.
When I select (edit / preview / go live) one of these songs, I get an exception (see below)

I still get the exception on all these songs, even when I change the author for the song in the db directly (table authors_songs).
I also changed the db entry for this author itself (changed the name), but the problem still occurs.

When I assign the author "Author Unknown" to a new song, everything
works, no exception.

  File "/home/oli/Programmierung/openlp/openlp/openlp/openlp/core/lib/mediamanageritem.py", line 472, in on_double_clicked
    self.on_preview_click()
  File "/home/oli/Programmierung/openlp/openlp/openlp/openlp/core/lib/mediamanageritem.py", line 494, in on_preview_click

    authors_none.append(author_song.author.display_name)
AttributeError: 'NoneType' object has no attribute 'display_name'
