Just to be sure, I re-downloaded ConTeXt Standalone (it's now on 2012.11.16), unpacked the newest simpleslides from modules.contextgarden.net in texmf-modules (overwriting the existing files), and, compiling my minimal example, got the same error.
I can confirm that the wiki still has the wrong version.
For what it's worth, I don't know how happy mkiv is with \doattributes and \dostartattributes.
Both commands are still working but when you write new code use the new macros from mult-aux.mkiv to set style and color values. Wolfgang
