CRASH REPORT Process <0.154.0> with 0 neighbours crashed with reason: fun called with wrong arity of 1 instead of 2 in mochiweb_io:'-iodevice_stream/3-fun-0-'/3 line 29

This is caused because Callback is called with arity of 1 here:
iodevice_stream(Callback, IoDevice, BufferSize) ->
F = fun (Data, ok) -> Callback(Data) end,

However, line 309 in mochiweb_request.erl uses send with arity of 2:
mochiweb_io:iodevice_stream(fun send/2, IoDevice)
