Finally, I've been successfull.
You have to run : gst-inspect-0.10 lame
This gives you all available options.

Then runs :
gnome-audio-profiles-properties and write in it what you want.

The one that works on my system is the following command line :
audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=0 vbr=4 
vbr-quality=0 vbr-max-bitrate=320 vbr-min-bitrate=192 ! id3v2mux

I got to reboot to make it works.

Hope that helps someone else. Francois
