Interesting. I'd like to understand better why the HTML builder doesn't do
this...it seems like a bug in the latex builder somehow.

So this absolutely needs to be "except sphinx.environment.NoUri". I have
seen catch-all "except" clauses paper over or otherwise hide too many
problems over the years; I really try to avoid ever using them.
I want to look at this problem and understand it a bit better; then I'll
probably end up applying this patch with the above tweak.
Thanks,
