It seems that there are only several classes that cause problems:
Products.CMFDefault.SkinnedFolder.SkinnedFolder
Products.Archetypes.BaseFolder.BaseFolder
Products.CMFCore.FS*
Products.Archetypes.BaseFolder.BaseFolderMixin

AFAIK most of the other classes with mro problems are just subclasses of 
these classes above.
