mysqldb error

[Firat KUCUK]

Hi,
i wrote a simple connection script.
It works as a command line script or cgi script.
But does not work in mod_python.

import MySQLdb
conn = MySQLdb.connect(
          host   = '127.0.0.1',
          user   = 'pismikrop',
          passwd = 'pass',
          db     = 'db')
print conn
conn.close()

command-line and cgi output:
<_mysql.connection open to '127.0.0.1' at 81a304c>

mod_python output:
<_mysql.connection open to '(null)' at 82ac504>

i cannot execute MySQL queries. What should i do?
