@David: I've got an oneiric setup where I found the error message introduced by your patch.

I get it when trying to connect to an AitTunes Remote Audio server on my LAN.

Did you get more information about what is causing this behavior ? Your patch added a /* FIXME */ which I'd love to disappear ;) Any freedback from upstream ? Should I re-open this bug ? File a new one ?

Hi Vincent,

Your bug is likely different from the original poster's bug. As I usually not deal with RAOP issues myself: if you have time to contact upstream directly (the <email address hidden> list is recommended) that would probably be your best odds of getting your bug fixed.
