Thanks for the notice. I'm glad somebody resurrected the MotionApp since it was a very worthy application. My favorite thing to have come out of the Rossum Project. And Python is an excellent choice. I awarded a star to your project of GitHub,
The problem is due to a TIFF format that is not supported by Commons-Imaging. I posted some notes to your bug report. I completed a code change and the fix is in the pipeline. Thanks for the test file. It helped a lot. If you have others (particular examples using a tile-organization rather than strips), I'd welcome them.
