# chemfig and MinionPro problem

Well, this is rather minor, but

\documentclass{minimal}
\usepackage{chemfig}
\usepackage{MinionPro}
\begin{document}
Hello, World!
\chemfig{*6(=N-*6(-N-=N)=--N-)}
\end{document}

produces

! Undefined control sequence.
<everyeof> @nil

but the output is fine, so far as I can tell. Why? (Btw, using MinionPro occasionally produces such errors with undefined this or that.)

Thanks!

One workaround is to force the font to load before your \chemfig command. For example \setbox0\vbox{$N$} will do so without producing any output (by typesetting a mathmode $N$ and then discarding the result).
