Can you try the latest version? There have been problems with spaces
[happens in strings] which were solved,

Indeed, that has been there for a short moment, some left over from testing.

that is (at least as far as i can test) solved by using a box instead.
There should be some 

\def\MPspacechar%
  {\setbox\scratchbox=\hbox{\char32}\kern\wd\scratchbox}%

code in there.

it was there purely for testing and i forgot to remove it, unfortunately
supp-pdf is coppied to other locations, instead of simply taking the one in
the context subtree. 

There are a few other changes, but these deal with improved clipping and
bbox issues but i don't think that that branch in the cod is used outside
context.

[if needed, you can convert mp graphics to stand alone pdf with the mptopdf
format which also takes care of things like shading, outline fonts, and
graphic inclusion in metapost code as well]

So, the solution to your problem is: fetch the latest context from our
site, unzip the cont-tmf file in the texmf root, and your latex will
probably work again; make sure that no other copies live on your system]
