pulseaudio 4.0 on Sabayon Linux

1.Start pulseaudio
2.run env PULSE_PROP_filter.want=echo-cancel mumble
3. pavucontrol: move the volume slider of Echo-Cancel Source Stream and
pulseaudio crashes.

The following way, I can move the volume slider of that stream and use
echo-cancel on mumble:
pactl load-module module-echo-cancel use_volume_sharing=no</pre>
