[Twisted-Python] callback errors?

[Posting this to twisted and zope3 user, since I'm not sure which is
more germane]

I just install zope 3.2.0 on Gentoo.
I then manually configured a zope instance in /var/lib/zope/zope-3.2.0/
When I access the zope server at 192.168.0.100:8080, I get the
following error messages on my terminal:

What do these mean?
How can I resolve them?
