This is more or less a duplicate of #980202To unblock gscan2pdf, in case -60 didn't fix things, I uploaded gscan2pdf-2.11.0-1 yesterday and replaced imagemagick with graphicsmagick for the tests in question.
However, this doesn't solve the problem in imagemagick, which is described in #980202, and for which imagemagick upstream claims to have a solutions, but evidently doesn't.
