[BUG] LaTeX: verbatim cannot be used in caption

[Timothy]

Hi All,

In exactly the same vein as
https://orgmode.org/list/87mtujfj8k.fsf@tecosaur.com/, verbatim text in
captions is very problematic with LaTeX (breaks compilation).

I'd like to be submitting a patch instead of a bug, but I'm not sure
what the best method of addressing this within ox-latex.el is.
Do share if you have any ideas :)
