 Please, where is the nesting? I suppose by "comment out the `Verbatim`
 environment that it's complaining about", you mean one of two `Verbatim`
 environments that were cited in comment:28.

 The first is
 {{{
 \begin{Verbatim}[commandchars=\\\{\}]
 \PYG{g+gp}{sage: }\PYG{k+kn}{from}
 \PYG{n+nn}{sage.categories.realizations} \PYG{k+kn}{import}
 \PYG{n}{Category\PYGZus{}realization\PYGZus{}of\PYGZus{}parent}
 \PYG{g+gp}{sage: }\PYG{n}{A} \PYG{o}{=}
 
\PYG{n}{Sets}\PYG{p}{(}\PYG{p}{)}\PYG{o}{.}\PYG{n}{WithRealizations}\PYG{p}{(}\PYG{p}{)}\PYG{o}{.}\PYG{n}{example}\PYG{p}{(}\PYG{p}{)}\PYG{p}{;}
 \PYG{n}{A}
 \PYG{g+go}{The subset algebra of \PYGZob{}1, 2, 3\PYGZcb{} over Rational
 Field}
 \PYG{g+gp}{sage: }\PYG{n}{C} \PYG{o}{=}
 \PYG{n}{A}\PYG{o}{.}\PYG{n}{Realizations}\PYG{p}{(}\PYG{p}{)}\PYG{p}{;}
 \PYG{n}{C}
 \PYG{g+go}{Category of realizations of The subset algebra of \PYGZob{}1,
 2, 3\PYGZcb{} over Rational Field}
 \PYG{g+gp}{sage: }\PYG{n+nb}{isinstance}\PYG{p}{(}\PYG{n}{C}\PYG{p}{,}
 \PYG{n}{Category\PYGZus{}realization\PYGZus{}of\PYGZus{}parent}\PYG{p}{)}
 \PYG{g+go}{True}
 \PYG{g+gp}{sage:
 }\PYG{n}{C}\PYG{o}{.}\PYG{n}{parent\PYGZus{}with\PYGZus{}realization}
 \PYG{g+go}{The subset algebra of \PYGZob{}1, 2, 3\PYGZcb{} over Rational
 Field}
 \PYG{g+gp}{sage:
 
}\PYG{n}{TestSuite}\PYG{p}{(}\PYG{n}{C}\PYG{p}{)}\PYG{o}{.}\PYG{n}{run}\PYG{p}{(}\PYG{p}{)}
 \end{Verbatim}
 }}}
 the second is
 {{{
 \begin{Verbatim}[commandchars=\\\{\}]   %% PROBLEM IS THIS LINE %%
 \PYG{g+gp}{sage: }\PYG{n}{A} \PYG{o}{=}
 
\PYG{n}{Sets}\PYG{p}{(}\PYG{p}{)}\PYG{o}{.}\PYG{n}{WithRealizations}\PYG{p}{(}\PYG{p}{)}\PYG{o}{.}\PYG{n}{example}\PYG{p}{(}\PYG{p}{)}\PYG{p}{;}
 \PYG{n}{A}
 \PYG{g+go}{The subset algebra of \PYGZob{}1, 2, 3\PYGZcb{} over Rational
 Field}
 \PYG{g+gp}{sage:
 
}\PYG{n}{A}\PYG{o}{.}\PYG{n}{Realizations}\PYG{p}{(}\PYG{p}{)}\PYG{o}{.}\PYG{n}{super\PYGZus{}categories}\PYG{p}{(}\PYG{p}{)}
 \PYG{g+go}{[Category of realizations of sets]}
 \end{Verbatim}
 }}}

 I suppose `%% PROBLEM IS THIS LINE %%` in the second environment was
 Jeroen's addition.

 So, what is "too deeply nested"? I can't believe that such a short piece
 of text has even enough characters to nest too deeply for latex!
