No (clear) way to disconnect or reconnect the StatusNet account

[larjona]

There's no place in the web ui where to disconnect or remove the StatusNet account you have connected. I tried to put my identi.ca account to force an error and maybe like this the field would be left blank, but it's not. I revoked the authorization in the statusnet account, and try to reconnect again, but I get an error:

URL (note the oauth_token) https://pump2status.net/authorized/statusnet/quitter.se?oauth_token=f1998716fa84fd309a20b4e17134353e&oauth_verifier=8df6fcb7aa866605

If I go to my quitter.se connections, I see:

Unknown application - Approved about 2 minutes ago - "read-write" access.
An anonymous application
Access token starting with: f108a69

Shouldn't the accesss token start with f19987 ?
