Hallo!
Here is a minimal example of how this happens. I had posted it sometime back.
\starttext \setupitemize[each][][stopper=:] \bTABLE \bTR \bTD \startitemize[a] \item Bla \item Blub \item Bautz \stopitemize \eTD \eTR \eTABLE \stoptext
Here is an other example! Remove the three-line-comment, and the error is gone! Strange what?
