CHECK(allow_empty_handle || that != __null) failed

This seems to happen from time to time when playing. I think that the buffer underflow always happens right before.

[../deps/mpg123/src/output/coreaudio.c:81] warning: Didn't have any audio data in callback (buffer underflow)

[1]    665 abort      node .

No buffer underflow, the first line is some additional logging I compiled in.

0x100810bf0STATE_LOGGED_IN

My additional code in session.cc, line 456:

// TEMPORARY
printf("%p", session->pointer);
sp_connectionstate s = sp_session_connectionstate(session->pointer);
switch(s) {
  case SP_CONNECTION_STATE_LOGGED_OUT: printf("STATE_LOGGED_OUT"); break;

}

Hmm, this might have something to do with this. I'm on a flight with crappy wifi right now so haven't really had the time to check it out, pardon me if I'm pointing anyone in the wrong direction.

I am encountering the same problem. Any other ideas on what is causing it?
