I uploaded a bunch of cjvu to Wikimedia commons where thumbnails failed to generate. Something seems wrong with the dvju conversion. E.g. for this one:
https://commons.wikimedia.org/wiki/File:1906_Lundby_f%C3%B6rsamling.djvu
I also get an error when I try to look at any jpeg-generated image from the djvu original file.
This issue is the same for several djvu files I've uploaded recently:
https://commons.wikimedia.org/wiki/Special:ListFiles?limit=500&user=Vitplister&ilshowall=1
Thanks for looking in to this!
