Thanks for the head up. I note that it built fine in sid a month ago:
https://buildd.debian.org/status/fetch.php?pkg=gscan2pdf&arch=all&ver=2.10.2-1&stamp=1608242025&raw=0 but that it didn't a couple of days ago in reproducible-builds: https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/gscan2pdf.htmlI guess something changed in the amd64 dependencies, because I can reproduce the problem now, too.
