How to avoid "Infinite glue shrinkage found in a paragraph." error with enumitem and nameref

Question

There seems to be a problem when combining the enumitem and nameref package. With the code below I get the error:

! Infinite glue shrinkage found in a paragraph.

I already checked the package documentation but neither package mentions the other as problematic in combination.

Removing the enumitem package gets rid of the error, but I need that package elsewhere in the document. This also shows the result that I am after, i.e. a cross-reference with the item label "Label".

Code:

\documentclass{article}
\usepackage{enumitem}
\usepackage{nameref}

\begin{document}

\begin{description}
\item [Label\label{Ref}] Text
\end{description}

\begin{itemize}
\item \nameref{Ref}
\end{itemize}

\end{document}

Answer 1

The nameref package uses gettitlestring that has code to support enumitem, but it is incomplete: it only manages \enit@format, but not \enit@align.

\documentclass{article}
\usepackage{enumitem}
\usepackage{nameref}

\makeatletter
\g@addto@macro\GTS@PredefinedLeftCmds{%
  \GTS@TestLeft\enit@align\GTS@Cdr % package enumitem
}
\g@addto@macro\GTS@DisablePredefinedCmds{%
  \let\enit@align\@empty % package enumitem
}
\makeatother

\begin{document}

\begin{description}
\item [Label\label{Ref}] Text
\end{description}

\begin{itemize}
\item \nameref{Ref}
\end{itemize}

\end{document}

Without the fix, the .aux file contains

\newlabel{Ref}{{}{1}{\enit@align {\enit@format {Label\label {Ref}}}}{}{}}

With the fix,

\newlabel{Ref}{{}{1}{Label}{}{}}
