LaTeX Error: There's no line here to end.

[floli]

I have this org document:

label:Testlabel Some citations cite:Bungartz2015 and cite:Torres2009 and a reference to a label ref:Testlabel

bibliographystyle:unsrt [[bibliography:/home/florian/Mendeley/library.bib]]

when exporting to a LaTeX file and run pdflatex -interaction nonstopmode test.tex I get

! LaTeX Error: There's no line here to end.

The latex file looks like that:

\bibliographystyle{unsrt} \bibliography{../../Mendeley/library} \\
% Emacs 24.5.1 (Org mode 8.2.10)
\end{document}

When I remove the \\ after the \bibliography it works.

I don't think this is an org-ref issue. It doesn't put \ in the exports for anything. I notice you have one at the end of the line starting with \label too. Have you configured something with paragraphs in org-mode?

[floli]

Nothing, all I configured when it comes to org / latex is:

                  org-latex-packages-alist '(("" "listings") ("" "color"))
                  org-latex-pdf-process '("latexmk -f -pdf %f")
                  org-latex-table-caption-above nil)

However, I was doing the compile manually, so pdf-prcoess is irrelevant here. I will try to reproduce it without org-ref, ask the org-mode list and report back....

[floli]

The settting org-export-preserve-breaks t causes the faulty export. Indeed not org-ref is to blame.
