[NTG-context] Making ConTeXt stop on all or some errors

Hi all, yesterday I asked about where to put color profiles. My problem was that ConTeXt for some unknown reason didn't find the color profiles I downloaded. But most annoying was the fact that I didn't saw the error in the log because ConTeXt only complains about not finding the profile. Is there a way to make ConTeXt stop if it does not find the profile like it stops if I use a unknown command? I want to avoid that we send a pdf without a profile to the print shop, because we overlook a message in the logs. juh
