omxmjpegdec hangs on Raspberry Pi Zero

[pinwheel]

When I test this pipeline omxmjpeg hangs and there is no output:

gst-launch-1.0 multifilesrc location="%04d.jpg" caps="image/jpeg" !
jpegparse ! omxmjpegdec ! multifilesink location="%04d.yuv"

With this pipeline I have no problems but is way too slow:

gst-launch-1.0 multifilesrc location="%04d.jpg" caps="image/jpeg" !
jpegparse ! jpegdec ! multifilesink location="%04d.yuv"

I have tested this with JPEGs created with raspistill. 

GST_DEBUG=3 doesn't show any errors. 

Hardware: Raspberry Pi Zero
Software: 
- Raspbian Stretch lite 2018-11-13 (kernel 4.14)
- gst-omx current APT package (1.10.4)
