[maemo-developers] [maemo-developers] Is this a bug in python-osso ? (osso rpc call with argument)

[From: Luciano M. Wolf]

Hi Pierre,

I did the tests that you propose on both emails and I achieved the
same results. I will file two bugs on pymaemo bugzilla[1] and will
take a look on this as soon as possible. Thanks for your reports!

Regards,
Luciano
