Weird layout of local collection in 2.4.x

[Jörg Schaible]

Hello,

my first attempt to use Amarok 2.4.0 (~ 11 months ago) failed, but now
I had finally to switch from Amarok 2.3.2 to Amarok 2.4.3, since the old 
version had some display incompatibilities after my update from KDE 4.7.4 to 
4.8.1. Unfortunately the problems with 2.4.3 are for me still the same as 
with 2.4.0. I understand that Amarok supports now an album interpret 
starting with 2.4.x.

My local collection is typically sorted with the interpret at the first 
layer and the album name at the second layer (incl. year). In 2.3.2 this has 
for some albums the unfortunate effect that they are added to the various 
artists, just because one song is e.g. a duet. With 2.4.x this album is 
moved out of the various artists and I get individual entries now, one for 
each interpret variation. OK, therefore I select in 2.4.3 now the album 
interpret as first layer and - hooray - all titles of the album are grouped 
together within one entry (well, if the titles have the album interpret 
set). Promising.

However, I have suddenly albums in the various artists that have not been 
there with Amarok 2.3.2. As it turns out, the titles of all albums with same 
name are now grouped together although the tags for interpret and album 
interpret are set correctly. E.g. I have suddenly an album "Up" in the 
various artists where the titles of the albums with this name of Peter 
Gabriel, R.E.M. and Shania Twain are mixed up (sorted alphabetically by 
track number and name). This prevents completely the selection of the 
individual album for the playlist. I have quite some of this annoying 
clashes (albums with name "Time", "Eden", "Zeitgeist", "Harpe Celtique", 
"Elemental", "Simply the best", "Hysteria", "Solo").

Another bunch of "new" albums for the various artists appear. All those are 
affected where the interpret is the same for all titles of the album, the 
album interpret is empty, but the composer may vary.

A manual run of the amarokcollectionscanner proofs that the tag info was 
properly read. Is there anything else I can do?
