Why package enumitem conflicts with Tufte-book and/or beamer

Question

Possible Duplicate:
Trouble combining enumitem and beamer

I am trying to produce a package, combining tufte-book and beamer, in order to produce lecture slides and handout (with explanations) for students from the same source. I found the useful hints in thread Beamer slides and tufte-handout.

I attach two sources. The file mwe.tex is essentially identical with that I found in that thread. The file main.tex contains a simple description:

\begin{description}
\item[OneItem] one item
\end{description}

It compiles fine. However, when I also add the line

\usepackage{enumitem}

then the compilation hangs as described by the conflict of tufte and beamer. When I comment out the 3 lines of the description, but keep the \usepackage line, the compilation is fine again.

I have found the thread Trouble combining enumitem and beamer but the patches described there do not work for me.

Any hints?

The two mentioned files: mwe.tex

            noxcolor,       % needed for cooperating with beamer
            ]{tufte-book}
