This is a weird one.

I loaded three songs into my iTunes by "The Arcade Fire " -- that is, erroneously including a trailing 
space.  After I noticed this, I corrected all the tracks, and have confirmed that they are correct in iTunes, 
on my filesystem, and manually gone through the "iTunes Music Library.xml" file and confirmed that all 
instances of "The Arcade Fire" no longer include a trailing space.  I've set up SlimServer to only get its 
information from iTunes and not scan the music library folder manually.

The bug is that SlimServer now has an entry for "The Arcade Fire" and another for "The Arcade Fire " -- 
once with a trailing space, once without.  If I drill into each file it is correctly referenced, but the artist 
appears to always have the trailing space, even if I came in from the corrected artist entry.  In the web 
interface there are two entries under "artist", once with a trailing space and once without:

			<tr> 
			<td class="nowrap"> Artist: </td>
			<td>
				
					<a href="browsedb.html?
hierarchy=artist,album,track&level=1&artist=3159&amp;player=00%3A04%3A20%3A05%3A6d%3Ab0" 
target="browser">The Arcade Fire</a>
				
					<a href="browsedb.html?
hierarchy=artist,album,track&level=1&artist=3106&amp;player=00%3A04%3A20%3A05%3A6d%3Ab0" 
target="browser">The Arcade Fire </a>
				
			</td>
			</tr>

Rescanning the library and restarting the server do not appear to make the old entry with the trailing 
space go away.
