Thanks for reporting. This was a Python 2.6 compatibility issue, which should be fixed by the above commit.

Just so I can calibrate with common usage: is there a reason that you're stuck with Python 2.6? The project is planning to move to 2.7-only in the next few releases and I'd like to know who that might leave behind.

[iluvdirt]

Great, thanks! And as far as 2.6 goes, I'm running Snow Leopard and 2.6 comes with the install. Don't think I'll have any trouble updating to 2.7 just haven't had the chance yet.

[sampsyo]

Ah, that makes sense—Snow Leopard is the last OS X to ship without 2.7. Thanks!
