I just submitted a pull request on github for my attempt at a fix for this. I've been a Pandora One subscriber for a while now and have always used that mp3-hifi setting. Were non-subscribers ever able to use that setting? Regardless, Pithos connects as if it were the Android client and it seems like Pandora no longer provides that audio stream to the Android client. My fix allows you to specify that you are a subscriber and then connects as the subscriber-only desktop client.
