Yes, I continued investigating today and found out who returned NOT_NEGOTIATED
and why.

1) A multiqueue loop tries to push a buffer on vorbisdec.
2) Vorbisdec (actually baseaudiodecoder) tries to renegotiate and fails because
the pad is flushing.
3) It returns NOT_NEGOTIATED, multiqueue sets that as its src result.
4) A buffer is pushed on the multiqueue, and it returns its src result, which
not conveniently is GST_FLOW_NOT_NEGOTIATED
5) All hell breaks loose (bis)

baseaudiodecoder should check if the pad was flushing after a failed
negotiation. The next patch does that.
