I think it is actually blowing up trying to validate access to the
'macros' object from your view.  I was able to work around that part by
adding the following view class:

- ----------------------  %< ------------------------------------
from AccessControl.SecurityInfo import ClassSecurityInfo
from Globals import InitializeClass
from Products.Five.browser import BrowserView

from Products.CMFCalendar.permissions import View

class CalendarWidgetView(BrowserView):
    security = ClassSecurityInfo()
    security.declareProtected(View, 'macros')
    def _macros(self):
        return self.index.macros
    macros = property(_macros, None, None)

InitializeClass(CalendarWidgetView)
- ----------------------  %< ------------------------------------
