It's a shame I can't edit comments on Launchpad: Please disregard my previous comment, I seem to have misread the issue, sorry for the noise.
The error message noted in the title of this issue exactly matches the problem that I ran into last weekend, which explains how this issue popped up rather prominently in the search results I got when I searched for the error message. The cause is different though.
Hopefully my pointer to the ubuntu-keyring issue will help some folks arriving here via Google :-).
