Here's what the developer had to say about this:
"""
Do it the other way around, first rotate then scale, that should
work. The reason most likely is that the size of the downscaled
isn't a multiple of 16. exiftran (unlike jpegtran) doesn't
handle that right now, it isn't needed for images coming
directly from the digicam.

This workaround worked.
