Weird bug in reading/writing/saving ratings

[GoogleCodeExporter]

Which version of Cantata?
r5687

Steps:
0.  Connect to a remote MPD server whose collection is duplicated on the local 
machine.
1.  Find an unrated track.
2.  Open track information dialog.
3.  Rate and Save the track.
4.  See that the rating is now listed in the Rating column.
5.  Reopen the track info dialog.
6.  See that the rating field is empty.
7.  Tools->Write Ratings to file
8.  Check the file with mediainfo and see that the rating was indeed written to 
the file, even though the info dialog displays an empty rating.

So, I guess you are now saying #641 is invalid? As you *can* save the ratings?

I think the ratings were saved, just the dialog not working correctly when a 
single track is selected.

Please update - is it now fixed?

No, issue 641 is about saving ratings to the database on a remote MPD instance, 
in which it apparently doesn't save them to the database at all.  In this 
issue, the ratings are saved to the database (connected to a local MPD, not a 
remote one), but the track info dialog does not seem to display the new rating.

I'll build r5697 and try it out.

I just realized that I contradicted my step 0 in my last comment.  Let me check 
into this...

Yes, this issue does seem to be fixed now.  Thanks.

And yes, I think issue 641 is fixed also.

While we're talking about ratings, let me mention one small thing that is 
probably not a bug, but you might want to consider.  Just now I was connected 
to a remote MPD, and I loaded ratings from file for all the tracks in the 
playlist.  Then I saved them to the database.  That worked, and then the 
ratings started appearing in the Rating column in the Play Queue.  Awesome.  :) 

What I am curious about is, the ratings appear slowly, one at a time.  
Eventually they all appear, so it is working correctly.  But when I connect to 
a different MPD server, and then connect back to the first one, the ratings 
appear all at once for all of the files.  So I wonder if you might want to 
batch this process together somehow.  However it's doing the query on initial 
connection, it seems like it could do the same thing here.

No big deal, really, but let me know if you want me to file this as an issue.  
Thanks.
