Some events that fire when objects are modified are also fire when the
changes are undone. In most cases, you check the IsUndoing property of the
notifying object, and do nothing if it it's true.

I have it narrowed down to the Database_ObjectUnappended event.
For some reason,
I can copy the group with my net deepcloneObjects and undo that without
problems,
but if I copy the group with the autocad command, then undo, it crashes.
I'll have to look at it some more.
