Favorite stations don't play anymore

i have 33 favorite stations in that playlist, and recently now when i double click on any station they do not play, i either get the loading indicator or just the little shoutcast lightning bolt.

I'm using Ubuntu 8.04LTS and Songbird is 1.1.1, Build 1018 (20090309145106), it is also happening under Songbird 1.1.2, Build 1042 (20090331141709) too. (I updated to see if that would fix it. nope)
