Does anybody else see this on a fresh checkout of the zope 2.10 branch? I think it's pretty new; I had a checkout last week where I didn't get any test failures. pw@pw ~/tmp/z2branches/2.10 $ python test.py -s zope.component Running tests at level 1 Running unit tests: Running: ................................................................................................................................................................................................................................................................................................................
