that was a tough one (esp because my by-now reference mkiv converter 
also had this problem)

in meta-pdf.mkii patch:

\def\flushconcatMPsegment
  {\ifcase\getMPkeyword\relax
     \flushMPconcatmoveto
     \resetMPmoveto
     \doMPconcat{\gMPs1}\a{\gMPs2}\b%
     \PDFcode{\!MP\a\space\!MP\b\space l}%
   \or
     \flushMPconcatmoveto
     \resetMPmoveto
     \doMPconcat{\gMPs1}\a{\gMPs2}\b%
     \doMPconcat{\gMPs3}\c{\gMPs4}\d%
     \doMPconcat{\gMPs5}\e{\gMPs6}\f%
     \PDFcode{\!MP\a\space\!MP\b\space
              \!MP\c\space\!MP\d\space
              \!MP\e\space\!MP\f\space c}%
   \or
     \bgroup
     \noMPtranslate
     \flushMPconcatmoveto
     \PDFcode{\!MP\lastMPmoveX\space \!MP\lastMPmoveY\space l S}
     \egroup
     \resetMPmoveto
   \or
%      \flushMPconcatmoveto
%      \resetMPmoveto
   \fi}
