well, i would consider what you observe a bug.  which processor did you
use in creating this profile?  incidentally, francis reported something
along these lines last week.  we should no doubt iron this out.

in principle, as of early 2007, all derivations should include the root
symbol that licensed them.  [incr tsdb()] is backwards compatible with
its treatment of derivations, i.e. it will successfully reconstruct and
treebank both variants (the root information is not needed for that).  

but for future parse selection experiments, i would expect the root may
prove a useful feature, hence we should aim to always have it reported.
