Output of the second pipeline with the -v option

rmdemux seems to find tags in Real Audio filea:

$ gst-launch -t filesrc location=ra/ilgattopardo/ilgattopardo1.ra \
! decodebin2 ! fakesink
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
FOUND TAG      : found by element "rmdemux0".
           title: Il Gattopardo  -  1 p.ta
          artist: Terzo Anello  -  Ad alta voce
       copyright: Copyright © 1997 2000 Netia Digital Audio
<more output...>

But it forgets to pass those tags over to other elements:

$ gst-launch -t filesrc location=ra/ilgattopardo/ilgattopardo1.ra \
! decodebin2 ! lamemp3enc ! id3v2mux \
! filesink location=ilgattopardo1.mp3
$ eyeD3 ilgattopardo1.mp3 
ilgattopardo1.mp3	[ 10.13 MB ]
-------------------------------------------------------------------------------
Time: 44:26	MPEG1, Layer III	[ 32 kb/s @ 44100 Hz - Mono ]
-------------------------------------------------------------------------------
ID3 v2.4:

No tags are found in the resulting MP3 files.
