* gst/effectv/gstquark.c: (gst_quarktv_set_caps),
(gst_quarktv_get_unit_size), (gst_quarktv_transform),
(gst_quarktv_planetable_clear), (gst_quarktv_change_state),
(gst_quarktv_base_init), (gst_quarktv_class_init),
(gst_quarktv_init): Flush the planes list on reverse caps
negotiation. This was crashing because of differently sized
buffers.
