In one of my recent Documents (using the beamer class) I used \wdthof to adjust the text width of (TikZ-) nodes. Last week I did a system-wide update, changing the installed TeX distribution which stopped the document from working.

This is a minimal example:

\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\node at (0,0) [text width=\widthof{Text }] {Text};
\end{tikzpicture}
\end{document}

Mark Wibrow suggested a workaround like

\catcode`@=11
\tikzoption{text width}{%
\pgfutil@in@\widthof{#1}%
\ifpgfutil@in@%
\setbox\pgf@hbox=\hbox{{\let\widthof=\relax\pgfutil@selectfont#1}}%
\edef\tikz@text@width{\the\wd\pgf@hbox}%
\else%
\def\tikz@text@width{#1}%
\fi%
}

\catcode`@=12

here:

Things like "text width=\paperwidth*\real{0.618}" should be made to work again, too.

I'm sorry -- I submitted the item while my account was still "pending". Thus it says "Submitted By: Nobody/Anonymous"
