Keyring python module and Mac OSX -

i'm trying use keyring python module on mac.

keyring.get_password

returns none, although pretty sure keyring , username in both exist. idea problem?

to give more concrete example, piece of code:

print "'{}' '{}' [{}]".format(keyring, username, keyring.get_keyring()) return keyring.get_password(keyring, username)

prints when invoke concrete arguments:

'login' 'skype' [<keyring.backends.os_x.keyring object @ 0x10c85b450>]
