Ok, so the deepest I���ve got is that ���self classWidget getClassesList��� (where self is NautilusUI) always returns an empty list, so removed class is not found in that list, so it is not removed from the model. I have not changes��ClassWidget and never worked with it, so from now the investigation will go slower. I���d appreciate help in any Nautilus people are out there.

this morning I started to read the method of AbstractNautilusUI now I still do not get what you did.
I hate that I have to download a special image and merge a special slice.
We should really have a diff in plain text as it is done in squeak sent to this mailing-list.
With that it would take me less than a second to see what you were doing.
