VCE encoding sometimes locks up since 4.8-rc1 (when simultaneously using vaapi decoding)

Running this gstreamer pipeline
gst-launch-1.0 -e filesrc location=big_buck_bunny_720p_1mb.mp4 ! qtdemux ! decodebin ! videoconvert ! omxh264enc ! h264parse ! matroskamux ! filesink location=/tmp/output.mkv
works fine on 4.7.
On 4.8-rc1 running it a couple of times randomly locks up the gst-launch process. Then while it hangs, running glxgears or so locks up everything.
On the plus side, when it works, it works a lot quicker on 4.8.
I'll look into bisecting unless someone else can reproduce and already knows why it happens.
