This is almost certainly a problem with how Debian is compiling or linking ghostscript with libjbig2dec. This error would be reproducible with:
gs -sDEVICE=pngmono -o out.png any_pdf_that_contains_a_jbig2_image.pdf Debian's test suite for ghostscript is just a simple smoke test, so ocrmypdf frequently uncovers problems with ghostscript.
