Hello I have a few longtabu's in a document, some of those use xcolor to slightly alternate the row color. I have been using something similar as below for more than a year now, but updating my texlive distribution breaks it (on Windows). It spews alot of the following at me, refering to the line containing \end{longtabu}
Missing } inserted. \end{longtabu}
Missing \cr inserted. \end{longtabu}
Misplaced \cr. \end{longtabu}
...
The minimal example:
\documentclass[10pt]{article}
\usepackage[a4paper,height=24cm,top=2.5cm,width=16cm,left=2.5cm]{geometry}
\usepackage{xcolor} % removing this line helps
\usepackage{longtable}
\usepackage{tabu}
\begin{document}
\begin{longtabu} to \textwidth{XX} % changing to l-columns works too
This is a & Test! \\
Using xcolor together with X-columns & doesn't compile.\\
This happens on recent windows distributions of & texlive. \\
\end{longtabu}
\end{document}
It works fine on my older Windows texlive installation and it works fine on a recent texlive distribution on ArchLinux. I tested everything on (scheme-full) installations. I also rebuilt the xcolor and tabu packages.
The problem seems to occur with the color-package as well.
TLDR; longtabu and xcolor/color don't work together on recent Windows texlive (13th January 2019).
Am I missing something obvious?
