Summary: Reference count bug in ODBC

Initial Comment:
The following code crashes -

import odbc
db = odbc.odbc('frank/Adminstrator')
 
def update():
    c = db.cursor()
    try:
        c.execute("insect into fmtest values ('rubbish')")
        return ['success']
    except:
        return ['fail']

print update()

The update routine tries to insert a record into the 
database. If it fails (it will in the example as the 
command is invalid), MSW pops up a box with the 
message "Python.exe has generated errors and will be 
closed by Windows", and the dos box displays the 
message "<refcnt 0 at ....>".

The error only occurs if the return type is a list, and if 
the function returns from the "except" clause.
