This has been happening to me this morning.  If I start pithos, the first song will play and then if I let it finish or click next, the remaining 3 songs all say Error: Resource not found, 4 more songs get queued and then immediately say Error: Resource not found.  Finally, a popup dialog is thrown which says Error Resource not found with a  Quit, Retry and Preferences buttonset.  I get the same behavior if I try a different station as well after this error starts.  If I close the app and re-open it, the first song always plays.  Here is the output from running it as --verbose:
