Upgrade complete, problem solved.

Big thanks to Richard for putting me on the right track again (in this case
2.7.2 to be specific :-)

2.6.5 is no longer maintained by us as a branch under source control.

Suggestion 1: Can you upgrade to Python 2.7?
Suggestion 2: We find the fix to this problem from the 2.7 branch, and
either you apply it locally, or we create a hg branch.

I think we should do the latter regardless, but if we can put it off
by you taking suggestion 1..
