ubuntu-sso-login crashed with ValueError in /usr/lib/python2.7/dist-packages/ubuntu-sso-client/ubuntu_sso/main/__init__.py: bad marshal data (unknown type code)

I just did today's Precise upgrade, which included ubuntu-sso-client 2.99.92-0ubuntu1. It looks like I had been running 2.99.91-0ubuntu1, previously, since March 21, with no problems apparent to me.

Update-manager suggested a reboot. I did so, and when logged in to the new session, apport soon came up with this SSO crash.

The same crash report has appeared once more, while I'm writing this.

I'm not using any Ubuntu services that SSO handles -- I don't think. Obviously I have this LP account. :)

Since I don't know much about SSO, I don't have a lot more to add -- oh well! Thanks.

This bug has not recurred under any later logins, with or without a full reboot.

That includes several tries under the version above, that crashed, and version 2.99.92-0ubuntu2, just released.

Status changed to 'Confirmed' because the bug affects multiple users.
