Are you, by any chance, concurrently accessing the same EC without
locking it?  If you do, then maybe you should probably re-read the
dedicated section in the User's Guide :)
http://modeling.sourceforge.net/UserGuide/framework-integration-MT-consider=
ations.html

  Operations on an EC is not thread-safe by default, and concurrent
  access w/o locking it first could lead to the behaviour you observe
  (where an object can be observed w/ a gID=3D=3DNone by a given thread
  while the fetch procedure is still processed in an other thread).
