Seems to be similar bug as http://sourceforge.net/
tracker/index.php?
func=detail&aid=1257960&group_id=5470&atid=105470 
(fixed)

Couldn't trigger with same script but with C 
application. Same source modification helps (at 
Objects/genobject.c:53)

This bug is blocking development of PostgreSQL Python based 
stored procedure language -- PL/Python.

Does this affect 2.5 or only 2.4?  There were a fair amount
of generator changes in 2.5.

2.5 is already fixed: http://sourceforge.net/tracker/
index.php?func=detail&aid=1257960&group_id=5470&atid=105470

2.4 has exactly same problematic assertion, even same 
modification helps. Fedora has fixed it in their 
distribution: https://bugzilla.redhat.com/bugzilla/

Python 2.4 is not actively maintained anymore. As this occurs in the debug build only, I recommend closing it as "won't fix". Just lowering the priority for now (svensoho, please don't change priorities).

I agree with Martin.  This is fixed in 2.5, but since we are no longer maintaining 2.4, it will not be fixed there.
