Wow! What a nice surprize!!!

I'm almost sure that this has to do with the fact that TikZ is broken
with respect to ConTeXt MKIV since 2009, but it has only been revealed
publically since a recent update of TikZ (a month or two ago). In
ConTeXt distribution we have frozen the updates of TikZ more than a
year ago, waiting for the patch to be included upstream ... I have
sent a working patch, but Till somehow left the project and I will try
some luck again convincing the others to patch it.
