[Pianod] segfault on 'rate neutral'

[Michael R. Hines]

I'm not sure whether this is a pianod bug or a pianobar bug, can you
advise?

When I use the command "rate neutral", here is the stack trace from GDB
when the segfault occurs:

mrhines at beethoven:~$ gdb pianod

..... snip ..... open terminal, play song and rate neutral.....

I've seen it do that rarely; it eventually continues when the request times out.  It's rare enough for me I've chalked it up as network or Pandora server dropouts.
