[dev-context] internal mptopdf not found in Context MkIV 2013.04.20

Partly to test Norbert's TeXLive 2013 packages for Debian, I just
installed the whole set of packages, which include Context MkIV
2013.04.20.  With it I get an error not present with the older (2012)
format, namely that the internal conversion of mps files to pdf fails.

I don't know whether it is a Debian-specific problem or shared with
upstream, hence I am also sending this to dev-context.

Here's the minimal example (mytest.tex):

  \enabletrackers[graphics.conversion]
  \starttext
  \externalfigure[fig/whole-tree.1]
  \stoptext

(You'll need an actual mps file of that name to get the error below.)

Then running it with

  $ context --trackers=list mytest

produces the error

  graphics        > inclusion > no converter for 'mps' to 'pdf'
  [MP to PDF]
  ! LuaTeX error [string "\directlua "]:1: attempt to index field 'mptopdf' (a nil value)

Here's the full log:
