WebKitGTK bubblewrap (aka bwrap) sandboxing and sndio

Hi,
  I found a bug with WebKitGTK and sndio, which is that if the sandboxing done
with bubblewrap is used, gstreamer errors out as it can't access the device.

I've found /tmp/sndio/sock0 but I'm not sure how this one should work as
I haven't found mention of it in the manpage and I'd rather avoid using code
as documentation.

Best regards
