audioconvert refuses to convert mono into stereo in Gstreamer 1.09

Hi,

channels=(int)1, channel-mask=(bitmask)0x0000000000000000

*is  INVALID caps for mono audio.*

channel-mask can be 
channel-mask=(bitmask)0x0000000000000001 , 0x0000000000000002 ,
0x0000000000000004 etc.

And regarding the bad pipeline example - 
GST_DEBUG=3 gst-launch-1.0 audiotestsrc ! avenc_g722 ! avdec_g722 !
audioconvert ! audio/x-raw, channels=2 ! fakesink

It did play for me in the latest gstreamer code.
