Hallo ConTeXt list member,

I am new member in the list so apologize if I ask for something trivial.
But I have been looking in documentation, in ConTeXt source code, in the
Net... Unsuccessfully. Perhaps someone here will known.

I have this simple file zk.tex:
%---------------------
\starttext
Hallo.
\startuseMPgraphic{zk}
  picture p;
  p:= btex Text1 etex;
%  p:= textext("Text2");
%  label(btex Text3 etex, origin);
  draw p;
  draw origin--(1cm,1cm);
\stopuseMPgraphic
\useMPgraphic{zk}
\stoptext
%----------------------

When I run
  texexec zk
the compilation pass successfuly but the result is without line
and "Text1". In the case of "Text2" I obtain line and "unknown" (picture)
text and in the case of "Text3" the same as in "Text1". The log file from
my recent context distribution on Linux web2c is in the attachment.

The file mpgraph.mpx is created with correct content (Text1). But next run
of metapost does not include it. The only way how to obtain desired
result is to run mpost directly
  mpost mpgraph.mp
But it is not possible with the "textext".

The instalation is standard. Only I set
  \setupoutput[pdftex]

  \usesymbols[nav]
  \setupsymbolset[navigation 1]

  \recycleMPslotstrue
  \runMPgraphicstrue
  \runMPTEXgraphicstrue
  \useMETAFUNformattrue
in cont-sys.tex

So, what I am doing worse?
Thanks
Vit
