[NTG-context] hanging with \bTD[nc=3]

Hello, With the latest ConTeXt-versions (current and beta), the compilation of the following test-files hangs with 100% cpu-usage: % engine=luatex \starttext \bTABLE \bTR \bTD[nc=3] x\eTD\eTR \eTABLE \stoptext No problem with nc=2. Cheers, Peter -- http://pmrb.free.fr/contact/
