I just upgraded to the latest beta in order to see if that would fix
my header styling issue. Compiling gave me the following error:
! Argument of \pgfutil@context@parse@gray has an extra }.
This is defined in:
tex\texmf-modules\tex\generic\pgf\utilities\pgfutil-context.def
If I change the code to the following (basically just comment out the
call to \pgfutil@context@parse@gray) then my document will compile
again. That's about my debugging limit - I shall stare at the code a
bit more to see if inspiration strikes.
% The cmyk part is from Joseph Wright.

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
