I don't get the error (I'm using MacTeX 2013 which is almost pure TL 2013 installed to the default location). Mojca On Sun, Jun 30, 2013 at 4:24 PM, Sanjoy Mahajan wrote:

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:
