Revit API collector: Could not cast value:spaces to target_type:

I don't understand why my code, which works fine with other revit categories:

# -*- coding: utf-8 -*-
import rpw
from rpw import revit, db, ui, DB, UI

dd1 = rpw.db.Collector(of_category='Spaces')

produces this error:

IronPython Traceback:

What target type? If your target type is rooms, the explanation is provided by The Building Coder discussion of Collecting all Rooms on a Given Level: You can't collect Room elements directly, because they are an artificial construct of the Revit API and do not exist natively inside of Revit. Therefore, you need to collect SpatialElement objects instead, the Room parent class, and post-process the results, e.g., cast them to rooms. See also Accessing Room Data and Filtering for a Non-Native Class.
