[Zope3-dev] ComponentLookupError after Unregistration

[Christian Lueck]

Hi list,

huuu, I yust unregistered a HTTPBasicAuthCredentialsPlugin from a PAU
and now I can't configure the hole PAU anymore, due to a
ComponentLookupError. Maybe my steps were not in the appropriate order,
but I think the ZMI should prevent me from stepping in an unappropriate
order.

I send you the hole traceback.

Regards,
Christian Lück
