This looks like a limitation of gst-launch. Link the pads by their
complete names, e.g. t.src_0 and q.src_0 / q.sink_0. Without that it's
also random which source pad and which sink pad are going together.

In general, at this point of pipeline complexity it is usually better
to write an actual application. gst-launch is only a debugging tool.
