Peter, what OS are you on?
Debian bookworm (=testing = pre12), daily updated. Aptitude shows "no unmet dependencies". Kpdf 4:14.0.13~pre6-0debian12.0.0+1~b1. To make it more mysterious: I have a pdf-file one year old, that i have opened in the past flawlessly with kpdf. Just tried to open it yesterday: screen shows 3 blank pages! Reinstalled, without any! alterations whatsoever and anywhere, from a backup kpdf-trinity_4%3a14.0.13~pre6-0debian12.0.0+1~a_amd64.deb from june 22nd and voila, my old pdf is readable again. BUT your Voronoi-file still shows only formulas.
More detail on the problem: konqeror file previewer actually renders the first side of the pdf with text, kpdf renders it without text. Is this reproduceable (Peter?)?
I haven't konqeror installed, mc does all what I need. But firefox shows all that abracadabra from your Voronoi, page 67 through 74:-)
Hope this helps to narrow down the search for the bug somewhere.
Kind regards, Peter.
