I fear I can confirm this.

"App.Management.Tabs.manage_workspace" apparently had the intention
to return "getattr(self,method)(self,REQUEST)" in the case that "method"
did not contain a "/", and to redirect otherwise.

Due to a bug in the the condition, however, it redirected for all
methods unless they started with a "/" (reported as a bug in the
Zope mailing list).
I fixed the condition (patch to collector 1058).

Unfortunately, returning "getattr(self,method)(self,REQUEST)"
requires the method to be DTML like and breaks if this is not the

I now think it is best to *always" use the redirect and never
return the method. My code now looks like:

        # DM: fixing the wrong condition now reveals a bug in WingDBG
        #     always redirect (as done earlier with the exception of
        #     absolute URLs)
        if 1 or m.find('/') >= 0:
            # DM: let absolute URLs work (as generated by
            #     "OFS.PropertySheets.PropertySheets.manage_options") 
            prefix= m.startswith('/') and REQUEST['BASE0'] or REQUEST['URL1']
            raise 'Redirect', (
                "%s/%s" % (prefix, m))

        return getattr(self, m)(self, REQUEST)
