I think I saw what happens with this adaptor-
In Bio::DB::BioSQL::DBAdaptor::_load_object_adaptor (call from 
create_persistent) there is request that this module is loaded:
There is no such module... This always fails, but since it is evaled, 
there is no actual error- instead. Perhaps this is leftover...?
This got me fooled...

I guess Chris could be right-
  Bio::DB::BioSQL::AnnotationCollectionAdaptor::_annotation_map_key is 
being passed Bio::Annotation::Collection as a value for $obj->obj(). Or 
recursing too far?
Anyway, I am just guessing here- I do not know the architecture of 
Thanks again for the help...
