Guayadeque Music Player

For a while Guayadeque has been far less responsive that usual. It greys out and freezes regularly. The reason why I've not commented on it before is because I couldn't associated the behaviour to anything in particular, but now I think I may have found it. It is to do with labels in playlists. From the playlist tab every time I try to do something with a playlist whose criteria is or includes a label Guayadeque freezes, greys out and CPU goes to near 100% for 15/20 seconds.

If I choose to play with smart mode using filters that contain labels it happens the same and some times Guayadeque freezes halfway through the song.

I cant see this behaivour here
