I got the same issue, and found a solution !
If you use the third parameters of Python function, you must declare the 
function
with METH_VARARGS|METH_KEYWORDS, and not only METH_VARARGS. Otherwise, the third
parameters will be invalid.

Here is a patch that can be applied on the latest svn (r259 right now)

The patch is applied (r260). No changes on my 32bits computer, I will test it on
64bits (OS X) tomorrow. Check it out on your side... Thanks again!

• Changed state: Fixed

Works well on OS X (64 bits), hope it's the same on linux!
