You probably shouldn't have, that could be where the error is.... I'd
include the whole function up to the call that raises the exception.

This should be return NULL in most cases, but not all (such as if it's
an object's tp_init--and it does look like that's the case here, so
probably not the issue).

Are you sure that PyArg_ParseTupleAndKeywords is what's raising the
error?
Are you subclassing this type in Python, and passing one of the string
parameters a tuple by mistake? For instance, did you do something
like this:
class myclass(_mycmodule._myctype):
def __init__(self,*args,**kwargs):
log_something_here()
super(myclass,self).__init__(args,**kwargs)
Note the missing * on args.

That it would have to be in a certain order is strange. Are you sure
it's just not merely that they all have to be present?

Tricky, but I think it'd help if you provided more information. My
gut feeling is that there exception is being raised somewhere other
than you think it is (i.e., not by PyArg_ParseTuple), so I'd recommend
adding some debugging statements to track down the exact point wher
the error occurs.
