Lots of problems with journal article tex's

[jaggzh]

So, many publications in arxiv.org have their pdf's as well as their source files available. I've had almost no success with conversions of their documents to html.
Here's just one example of many:
https://arxiv.org/format/1708.01692
The PDF is there, with the "source" file (named .bin, but it's a tar).
I'm currently using a command-line like:

latex2html -noshow_section_numbers -verbosity 1 -no_math -split 0 -dir html whatever.tex

I get a lot of failed images (it seems the temporary image file is 0 length. I had to modify latex2html to examine that). Here's a failed image output error:
Converting image #75
pstoimg: Error: "/usr/bin/pnmcrop -verbose < /tmp/l2h1347/p16645.pnm > /tmp/l2h16347/p16645.t00" failed: Illegal seek

Again, that seems to be after the broken creation of the .pnm

Here is the full run's output:

Thanks a lot. I hope someone can help.
