Where and when do you call gst_pad_has_current_caps()? In the pad-added
signal of rtpbin on one of the rtpbin pads? That might be fixed by this
recent commit:
http://cgit.freedesktop.org/gstreamer/gstreamer/commit/?id=8162a583a4dd68582bf186e2e47a8f0d68fa1980

Otherwise, do you at least get the caps soon after the pad-added signal,
i.e. is the notify::caps signal emitted on the pad? That would work as a
workaround but the caps should really be known already when the pad is
added.
