Version:           2.0.2 (using 4.2.2 (KDE 4.2.2), Kubuntu packages)

I am running Amarok 2.0.2 on a fresh installation of Kubuntu 9.04.

Suppose I have a playlist of songs p1, p2, p3, p4, p5, ...
If I filter the playlist, it displays the songs f1 = p2, f2 = p4, f3 = p5, ...

The problem arises when I try to queue tracks from the filtered playlist -- selecting, say, f2 results in p2 being queued instead. More generally, attempting to queue the ith track from the filtered playlist results in the ith track from the *un*filtered playlist being queued instead. 

This makes it very difficult to manage queues for a large playlist.
