cannot avoid gnome-keyring under gnome

[misc]

If you start gajim on a computer with gnome-keyring, it will ask you to create a keyring to store the password. However, if you click on "deny", it should fall back on regular storage, and instead, i see this traceback :

Traceback (most recent call last):
  File "gajim.py", line 2481, in <module>
    Interface()
  File "gajim.py", line 2343, in __init__
    gajim.connections[account] = common.connection.Connection(account)
  File "/home/misc2/checkout/svn/gajim/src/common/connection.py", line 118, in __init__
    self.password = passwords.get_password(name)
  File "/home/misc2/checkout/svn/gajim/src/common/passwords.py", line 124, in get_password
    return get_storage().get_password(account_name)
  File "/home/misc2/checkout/svn/gajim/src/common/passwords.py", line 111, in get_storage
    storage = GnomePasswordStorage()
  File "/home/misc2/checkout/svn/gajim/src/common/passwords.py", line 51, in __init__
    gnomekeyring.create_sync(self.keyring, None)
gnomekeyring.DeniedError

Here is a patch.

I have a similar error when i say "save the password" and i do not allow to acces to gnome-keyring :

Traceback (most recent call last):
  File "gajim.py", line 1876, in autoconnect
    self.roster.send_status(a, 'online', message)
  File "/home/misc/checkout/svn/gajim/src/roster_window.py", line 3339, in send_status
    passwords.save_password(account, passphrase)
  File "/home/misc/checkout/svn/gajim/src/common/passwords.py", line 129, in save_password
    return get_storage().save_password(account_name, password)
  File "/home/misc/checkout/svn/gajim/src/common/passwords.py", line 86, in save_password
    display_name, attributes, password, update)
