this has to do with the text passed to goto being submitted to quite 
rigourous manipulations; footnotes are inserts and inserts, like marks and 
other funny nodes often spoil things, so here the solution is it to carry 
over the footnote:

\def\donaar#1[#2]%
   {\dontleavehmode
    \bgroup
    \postponefootnotes
    \doifreferencefoundelse{#2}
      {\doifelsenothing{#1}
         {\dosymbolreference{}{}[#2]}
         {\donaarspace{#1}[#2]}}
      {\unknownreference{#2}#1\relax}% \relax catches lookahead
    \egroup
    \referentieinfo{<}{#2}}

You can put this in the file "cont-new.tex" and see if it solves the problem

indeed, if you want to refer to something, you use \in {something} [ref] or 
\at {somepage} [there] and alike; \reference just creates one, taking an 
argument which is to show up as reference:

%D There are three ways of defining a reference:
%D
%D \pagereference[here]
%D \textreference[here]{some text}
%D
%D the third alternative combines them in:
%D
%D \reference[here]{some text}
