Hi, Alex,

@sjMoquin That's also an Angstrom image? I'm not technically supporting Angstrom these days since the Debian builds have been the only images maintained and supported by BeagleBoard.org - you shouldn't have any trouble if you update...

That said, it looks like I'm not catching an error in the I2C C extension, which isn't very good... I'll look into it...
