Search filter in 3.3 no longer restricts playable tracks

[akaIDIOT]

After moving from exaile 3.2 on linuxmint 14 (12.10) to exaile 3.3 linuxmint (13.04) the search filter for the current playlist no longer restricts the playable tracks. In 3.2, I could search for "Brant Bjork" and exaile would only play tracks matching that search whenever I pressed next. In 3.3, it keeps selecting tracks from the unfiltered playlist (unwanted behaviour for me).

In short:
- linuxmint 15 (based on ubuntu 13.04)
- exaile 3.3 (was 3.2)
- expected behaviour: filtered playlist becomes set of tracks to play from
- observed behaviour: filter results are ignored for selecting next track

(not sure if I was using this 'bug' as a feature or if this should be considered an actual regression, but I'm back to 3.2 because of this)
