Ok, that one was easy to fix:

    videomixer: Maintain z-order when new pad are added

    https://bugzilla.gnome.org/show_bug.cgi?id=701109

This makes me notice that the sinkpads list is not thread safe, which mean
changing zorder, creating new pad, or removing pads at runtime may lead to
crash if done while streaming thread is iterating the list. Will file another
bug.
