When loading some Monticello packages (e.g., VRML in the hedgehog
contrib repository, and some of my own), I get a key not found error
within MCClassDefinition>>createClass. This always happens when
Monticello decides that a "reload" is necessary.
What's up with that?
This does not happen with the version of Monticello that was in the
SDK beta (-ar.288), but only with the newer versions that are there
now. (I think the older MC does not try to reload, FWIW.)
