Bug 280999

Version:           2.4.3 (using KDE 4.6.5) 
OS:                Linux

Automatic Playlist Generator is not adding any songs to playlist after selecting ing a preset and clicking generate. the automatic playlist generator grey's out and i can't select other presets anymore.
tried with different preset settings and optimization still the same result.

Reproducible: Always

Steps to Reproduce:
playlist->automatic playlist generator->select a preset and click generate

Actual Results:  
no songs added to playlist after clicking generate. after clicking generate i cannot select anyother preset and do it again as the apg interface freezes

Expected Results:  
apg to add songs to list and allow me to generate playlist again

when running amarok with --debug flag got the following output.
