WARNING: erroneous pipeline: could not link vorbisenc0 to queue1

This one works:

gst-launch filesrc location=BigBuckBunny-stereo.flac ! flacdec ! audioconvert !
vorbisenc ! queue ! mux. filesrc location=big_buck_bunny_360p24.y4m !
ffdemux_yuv4mpegpipe ! theoraenc ! queue ! matroskamux name=mux ! filesink
location=big_buck_bunny_360p24.ogv

The only difference is the order of the audio and video pads. matroskamux's
audiosink_templ and videosink_templ are both request pads, so I don't really
see what could be causing this.
