That is not the error message. Error messages begin with a "!" at
the beginning of a line. The full message is:

   >> unknown string A.lines0
   >> picture
   ! Equation cannot be performed (unknown string=picture).

The first two lines are informational, telling you what exactly
was equated.

The documentation of metauml says

   ``A note is created as follows:
       Note.name(list-of-lines);
   The suffix name is the name of the Note object. The comma separated list of
   strings, list-of-lines, gives the text contents of the note 
object, each string
   being drawn on its own line.''

So it is clear you must use string parameters for Name.A.
If on some system metauml accepts btex etex, then either
it has a different version of metauml or it was accidental
that it worked.

It is possible in MetaPost to handle different types of
expressions in the same parameter, so it is possible some
prior version allowed btex-etex. I don't know. My version
(metauml 0.2.3) doesn't allow it.
