[Python-modules-team] Bug#892949: Bug#892949: mark decorator packages Multi-Arch: foreign

[Yaroslav Halchenko]

Sorry for the late follow up -- would you happen to remember why pymvpa2
is listed as effected?  AFAIK we do not use python-decorator, thus we do
not build- or run depend on it.  So why are we affected?
