As you quite rightly point out in a subsequent message this is a
problem in Albatross.  Looks like a 2.2ism sneaked in there.

Andrew and I discussed which level of Python we should target now that
1.5.2 is a distant memory and we settled on 2.1.

We need to fix this for the 1.10pre2 release that I hope to get out
before the end of the week.

If the 1.10pre2 goes well we will rerelease it as 1.10 and announce
it outside of this list.
