I applied this patch.

I noticed Philipp fixed a bug in the sink->source pad format
propagation. I was only propagating the active runs, and not
the trial runs. I fixed this everywhere in the pipeline, applied
to the "propagate sink pad formats to source pads" patch. Try
runs should now work correctly across the whole pipeline, but
I haven't tested this.
