Yes, this is correct. In this example, queue ends up being linked to a pad that
isn't shown in the pad template for mpegdemux, which is there because mpegdemux
derives from mpegparse and isn't removing the pad (which it probably should do)

In any case, the correct solution is to ensure that queue gets linked to the
correct pad of mpegdemux by either:
a) specifying a pad in the launch line, eg "gst-launch filesrc location=<a mpeg
file> ! mpegdemux .video_00 ! queue { ! mpeg2dec ! xvimagesink }"
b) In an application, perform the link yourself by connecting to the 'new-pad'
signal of mpegdemux and linking it to the queue only when a video/mpeg pad is
created.
