To lift a quote from
When deleting an item from the FolderBrowser "delete" link, the
item being deleted is a ContentBundle, therefore all instances are
deleted by persistence automagically. However, there is only one
problem, observers are not run because the domain objects for the
instances are not instantiated.
Fixed on the trunk in change 41632.
When backported to Troika, this also fixes bug 116010 (see comment #12).
