Every time I try to open a particular pdf I'm inundated with "Org parser
error"s, all looking like this:

>  Warning (org-element-cache): org-element--cache: Org parser error in
thesis.pdf::316345. Resetting.
>  The error was: (error "rx ‘**’ range error")
>  Backtrace:
> nil
>  Please report this to Org mode mailing list (M-x org-submit-bug-report).
> Error (pdf-view-mode-hook): Error running hook
"pdf-tools-enable-minor-modes" because: (error rx ‘**’ range error)

I had a similar problem with the .tex source for the pdf too briefly. I
have a sneaking suspicion that it's to do with the fact that I recently
removed a large chunk from each document. (The line thesis.pdf::316345
doesn't exist.)

Is there any way I can disable org-element-cache on pdfs as a
workaround?

Thanks,
Sam
