Seems like Doxygen generates LaTex incompatible with recent versions of
pdflatex [1,2,3]. Probably it is this Doxygen bug:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1114478
There appears to be a workaround [4] but not sure if it is a good idea
to apply it. I think my preference would be to drop the libest-doc
altogether as it only contains the generated PDF.
