Hi Theo,

This looks new; ANNOTATE-FOR-SINGLE-STEPPING in
collects/mztake/annotator.ss used to take in five arguments, but it looks
like it now takes six.  Checking svn... it looks like the change in r2071
might be it.

bash-3.00$ svn log -v -r2071
------------------------------------------------------------------------
r2071 | gmarceau | 2006-02-01 11:05:04 -0800 (Wed, 01 Feb 2006) | 1 line
Changed paths:
   M /trunk/collects/mztake/annotator.ss
   M /trunk/collects/mztake/engine.ss
   M /trunk/collects/mztake/mztake-structs.ss

implementing top-level-ids
------------------------------------------------------------------------

Perhaps you might want to revert back to a version before r2071 until this
is fixed?


It looks that that sixth parameter needs to be a "record-top-level-id".
I'm not familiar enough yet with mztake's internals to figure out what
appropriate value to place in there.


Good luck!
