[NTG-context] \cite fails with “Extra ...”

Hi all, when updating some module documentation I came across this one: ································································· \startpublication [ k=mt, t=book, a={Bodoni}, y=1818, n=1, s={Manuale}, ] \author[]{Giambattista}[]{}{Bodoni} \pubyear{1818} \title{Manuale Tipografico, 2~vols} \city{Parma} \stoppublication \starttext foo \cite[authoryear][mt] bar \stoptext ································································· This definitely works with the beta from 2011-11-04, but not with the one from 2012.01.25. Has there been a change? Regards Philipp
