I found the bug. It comes from the definition in core-des:

\def\special@@definitiewoord#1#2#3#4[#5]#6#7%
  {\strut
   \doifelsevalue{\??dd#1\c!nummer}{\v!nee}
     {\!!doneafalse}

   \iflocation

          [ \v!lokaal=>\chardef\definitiekoppeling=1, % old: default
           \v!globaal=>\chardef\definitiekoppeling=2]}% new: global crosslinking
   \fi
   \stelnummerin % the number is called indirectly

         %\in[\localconnection]%
        \fi\fi}%
     \doifnot{#5}{-}{\rawreference{\s!num}{#5}{#3{#1}}}%
% Here is the bug -----------------------------^^^^^^
% When this gets called with \showdnnummer as #3, there
% is an expansion problem, since \showdnnummer is *not*
% properly expandable: it uses the command sequence
% \preparednumber which is defined by \showdnnummer itself
% If I change the line with something like

       \preparednumber
       \nummer[\getvalue{\??dd#1\??dd\c!nummer}]}%
     \doifnot{#5}{-}{\rawreference{\s!num}{#5}{\thenumbertouse}}%
% everything goes on smoothly.
% Maybe we need and expandable version of showdnnummer?
   \else % Why was this strange expansion needed?
