1.4.2-beta1: Collection scan fails to correctly group multi-artist album tracks in Context Tab

Version: 1.4.2-beta1
engine: xine

Info:  Approx. 2000 mp3's.  Organized by filename (artist_-_track) only, (rely on ID tag scanning for other info).  Four music folders organized alphabetically, (folder 1 has artists A-E, etc).  Each folder has about 4GB of mp3's.

Problem:  Album-1 has Artist-1 and Artist-2.  Album-2 has Artist-1, Artist-2, and Artist-3.  After a collection scan,  The Context Tab will automatically group Album-2 artists together (ie one album cover, with three different artists and tracks listed under it).  Album-1 artists are not automatically grouped together (i.e. playing Artist-1 from Album-1 will never list Artist-2 in the album information area and vise versa) UNLESS one of the following occurs:

1:  By selecting "Show under Various Artists" in the Collection Tab for the album
or
2:  Both artists are located in the same directory

This seems to only be the case (for me) when the number of various artists per album is 2.  Three or above are automatically grouped in the Context Tab correctly regardless of where they're physically located.  I only noticed this when I resorted my collection on disk so it may be an issue beyond the current beta.  (At least I think its an issue.)

WishList:  In the Collection Tab, when you right-click on an album and the album is already listed under Various Artists, there should be some indication, like a greyed-out "Show under Various Artists".
