The usage of the quotes library together with \usepackage[ngerman]{babel} results in the error:
! Argument of \language@active@arg" has an extra }.
MWE:
\documentclass[tikz]{standalone}
\usepackage[ngerman]{babel}
\usetikzlibrary{quotes}
\begin{document}
\tikz\node [draw, "label"] {A};
\end{document}

Thank you and best regards Elke
Closing issue. Improving the error message would be cool, but I think we can live with it for now
