--- Comment #1 from Guillaume Desmottes <gdesmott at gnome.org> 2011-09-09 09:04:13 UTC ---
Interesting. Looks like we are passing NULL to

Here is the code:

  color = gst_bin_get_by_interface (GST_BIN (src), GST_TYPE_COLOR_BALANCE);

  if (color == NULL)
    goto out;

  balance = GST_COLOR_BALANCE (color);

  channels = gst_color_balance_list_channels (balance);

So, color is not NULL but balance is, which means that color doesn't actually
implement GstColorBalance which sounds like a bug in
