[NTG-context] Pdfselect in texexec not working!?

Hi, I use ConTeXt minimals (MkIV, MTXrun | current version: 2011.01.18 19:34) and want to select a few pages from a larger pdf-file using the familiar --pdfselect switch from texexec. However this option is not working any more; the run ends with the following error message: ..... (\end occurred inside a group at level 1) ### simple group (level 1) entered at line 17 ({) ### bottom level No pages of output. Transcript written on texexec.log. TeXExec | runtime: 1.237985 Perhaps something has changed of which I am unaware? Regards, Gerard Verhaag
