Error en mod_python

[Percy Gonzales]

Hola, estoy en procura de configurar trac  (en realidad me ha ido muy
bien al instalarlo y esta funcionando en modo stanalone), pero al
momento de querer configurarlo para que corra en apache con mod_pyton
me da el siguiente error en el browser :


Mod_python error: "PythonHandler trac.web.modpython_frontend"

Traceback (most recent call last):

  File "/usr/lib/python2.3/site-packages/mod_python/apache.py", line

    result = object(req)

  File "/var/tmp/python-sqlite-root//usr/lib/python2.3/site-packages/sqlite/main.py",
line 244, in execute

DatabaseError: unsupported file format





Mi configuracion de virtual host es la siguiente:

<VirtualHost *:80 >
    DocumentRoot /www/trac/prueba
    ServerName trac.dominio.com
    ErrorLog logs/trac
    CustomLog logs/trac common
    <Location />
        SetHandler mod_python
        PythonHandler trac.web.modpython_frontend
        PythonOption TracEnv /www/trac/prueba
        PythonOption TracUriRoot /
        PythonDebug on
    </Location>
</VirtualHost>



Me podrian ayudar a resolverlo por favor


gracias
