\about does not support \about{...}[...] kind of references like \in or
\at. Does some documentation say that this is supported? This is what
core-ref.tex says
\definecommand about {\dospecialabout}
...
\unexpanded\def\dospecialabout[#1]%
{...}
This explains the error message that you get when you try \about{foo}[aa].
What do you want to achieve with \about{foo}[aa]? There may be some other
way to do that.
