[Pharo-users] strange cache behaviour for DSAdaptiveModel magritte description

Does any one have any insight into the caching of magritte descriptions for DSAdaptiveModel? What I see is that there seem to be multiple copies of the description elements. A problem appears when a MACachedMemento seems to have a different description instance (a different hash value anyway), but the rest of the values seem to be the same as the other copy.
