Further investigation suggests that this is a known issue of using \definecolor colours within a Tikz graphic that decided to manifest itself for the first time when I upgraded. The solution is to do: \unprotect \pgfutil@definecolor{colour_name}{rbg/cmyk/gray}{...colour values...} \protect for all the colours that you want to use. Apologies for the noise. Felix
