It took me a while to figure this one out. It's not actually an API
change but a side-effect of the tempstorage tests reusing some ZODB
tests.

I fixed it in 
https://mail.zope.org/pipermail/zodb-checkins/2010-September/012464.html

tempstorage always loads the data in _finish and thus tripped over the
invalid payload of a simple 'x' string in those tests. The normal ZODB
tests don't care about the data payload and thus were happy to ignore
the invalid data.

With current ZODB trunk I don't get any test failures anymore inside
Zope2. So once 3.10.0b7 is out, we can upgrade to it.
