Hi Nop. Thanks for the report. I've been busy with prep for the 0.7 release so tracking down this issue after Philip originally reported fell off my radar( as I had planned to look closer).
Will do as soon as possible unless one of the other devs gets to it before me. Could you also send an email to Mapnik-dev?
