Here my report.
Now it manages to download and create a playlist.
But that is it. Something in the clients I tried (I tried VLC, AIMP2 and foobar) isnt very fireflyfriendly. They manage to shoot down the mt-daapd with an out-of-memory error.
Some simply get me a file not found and some fill the log file of firefly with crap.
Cant say where the bug is. Likely a bit with mt-daapd and also with the streaming progs and your playlist. Something just doesnt work together.
See this for details:
