Amarok not adding newly added files to my collection

[Frederik Himpe]

Hi, this problem has been bugging me for months (at least). When I add 
new files to the directory where my music is stored, and for which Amarok 
is configured to watch for changes, these files do not appear, until I 
rescan my whole collection by hand. The option "Update Collection" does 
not suffice. Rhythmbox on the other hand, which watches the same 
directory, immediately sees the files.

I have been looking for help on the IRC channel in the past already, and 
I thought I had found some possible causes. I was told that Amarok does 
not detect new folders if these are at the root level of a mount point 
(if this limitation is true, I think this really should be fixed, as this 
is a very common situation, and other applications handle this fine). My 
music is stored in /mnt/Music, which is an XFS file system on a seperate 
partition. But even when moving a new folder to an already detected 
subdirectory of /mnt/Music, Amarok still does not add the music.

So now currently I have a new album, which is stored in /mnt/Music/Pearl 
Jam/Osunlade/Elements Beyond/, which is not detected, although the other 
contents of /mnt/Music/Pearl Jam/ are already in the collection. I found 
also this: cat ~/.kde/share/apps/amarok/collection_scan.files
/mnt/Music/Pearl Jam/Osunlade/Elements Beyond/01. Osunlade - A Cloudy 
Mist.ogg
[...]

So the files actually have been scanned?! I saw no errors in ~/.xsession-
errors

These files can be played without any problem with Rhythmbox, and the 
tags are valid:
$ ogginfo "/mnt/Music/Pearl Jam/Osunlade/Elements Beyond/01. Osunlade - A 
Cloudy Mist.ogg"
Processing file "/mnt/Music/Pearl Jam/Osunlade/Elements Beyond/01. 
Osunlade - A Cloudy Mist.ogg"...

I hope somebody can help me finally debugging this annoying problem, so 
this can be fixed for ever.
