[sqlalchemy] SystemError: null argument to internal routine

[robert rottermann]

Hi there,

when testing one of my routines I get a strange error.
SystemError: null argument to internal routine
this is the method I call:
    def getExistingDoktypes(self, typid=0):
        "return tuple with ((typid, typ), ((typid1, typ1), (typid2, typ2), ..))"
        session = self.getSession()
        s = 
doctypCL.__table__.select()#[doctyp.c.typid,doctyp.c.doctyp,doctyp.c.subtyp,doctyp.c.topleveldir])
        records = session.execute(s)

I am using sqlalchemy 0.6.6
The DB is Postgress

thanks for pointers where to fix this error
robert
