Hi there,

I've been trying to use the new citation facilities in the just-released
9.5 version of org for a simple test document with my preferred CSL
style (the one usually used in German law discipline in one way or
another), but did not have luck with it so far. That being said,
exporting with the default "bare" citation processor appears to be fine.
With the "csl" processor, I receive this error when I export to LaTeX
with `org-latex-export-as-latex':

This is the test document:

    #+TITLE: Test
    #+AUTHOR: Testauthor
    #+LANGUAGE: de
    #+bibliography: /tmp/mwe/test.bib
    #+cite_export: csl /tmp/mwe/juristische-schulung.csl

    Das ist ein Test [cite:@goldsmith-wu2008netctrl p. 83].

I stored it in /tmp/mwe/mwe.org. This is the entirety of test.bib:

    @Book{goldsmith-wu2008netctrl,
    	author = {Jack Goldsmith and Tim Wu},
    	title = {Who Controls the Internet?},
    	year = {2008},
    	langid = {english},
    	publisher = {Oxford University Press},
    	location = {New York},
    	isbn = {978-0-19-534064-8},
        signature = {I/R/5}
    }

The used CSL style juristische-schulung.csl has been copied verbatim
from the CSL repository here:
https://github.com/citation-style-language/styles/blob/e22b8a566bad9b4c7f52720f60dd875057a5d210/juristische-schulung.csl

Steps to reproduce:

1. Create /tmp/mwe/mwe.org, /tmp/mwe/test.bib, and
   /tmp/mwe/juristische-schulung.csl with the aforementioned contents.

2. Visit /tmp/mwe/mwe.org.

3. Export to LaTeX with C-c C-e l L

4. Observe the above error.

What was expected: that it does not crash and exports fine.
