ConfigParser.NoOptionError: No option 'consumer_key' in section: '1'

[Martin Pool]

After logging in for the first time with Launchpadlib on a particular machine on natty, a second use of it fails as follows:

% ./traceback-into-bug-description 748801
Traceback (most recent call last):

    raise NoOptionError(option, section)
ConfigParser.NoOptionError: No option 'consumer_key' in section: '1'

I don't know yet which file it's looking in.

credentials.py line 322 is in the KeyringCredentialStore, so I guess that launchpadlib has written something in there that it cannot read back?

I can see it's written a new entry whose description is just "network password" and the "password" field of it is just "
the 3-byte string "[1]". That is not actually my password. From looking at the code I guess it's meant to be a ConfigParser ini-style file, but for some reason it isn't.
