[NTG-context] columnset BUG - (urgent!)

Hi, please have a look at testfile below: without a footnote everything works fine, but with the footnote the columnset gets crashed! I noticed this bug in a bigger book project: The columnset is at the end as a seperate document (\component). And the footnote was added 300 pages and 5 component files before !!! As this footnote was one of the last changes that were done before I wanted to send the book to the printer a fast help would be very much appreciated. Sorry, but it's really quite urgent - Steffen %&context \starttext \chapter{Heading\footnote{x}} \definecolumnset[litera][n=2,distance=1cm] \startcolumnset[litera] \dorecurse{10}{test \input zapf \input ward} \stopcolumnset \stoptext
