preconstructed rtp packets that break decoder

when frame sizes fluctuate, the gstreamer opus decoder breaks. I think it fails
to handle the buffer too small error in FEC mode:

running the following breaks the stream:
gst-launch-1.0 multifilesrc do-timestamp=true location=./c%04d.rtp
caps=application/x-rtp ! identity datarate=10000 ! rtpjitterbuffer do-lost=true
! rtpopusdepay ! opusparse ! opusdec plc=true use-inband-fec=true !
autoaudiosink

while this works (FEC off):
gst-launch-1.0 multifilesrc do-timestamp=true location=./c%04d.rtp
caps=application/x-rtp ! identity datarate=10000 ! rtpjitterbuffer do-lost=true
! rtpopusdepay ! opusparse ! opusdec ! autoaudiosink

Also works for reference: 
gst-launch-1.0 multifilesrc do-timestamp=true location=./c%04d.rtp
caps=application/x-rtp ! identity datarate=10000 ! rtpjitterbuffer do-lost=true
! rtpopusdepay ! matroskamux ! filesink location=out.mkv

ffplay out.mkv
