"I installed the unstable package polly_0.93.12~ubuntu14.04.1.tar.gz from the PPA" makes no sense. Why are you installing a tarball from the PPA instead of simply adding the PPA to your repository list?
The error message indicates that GNOME Keyring might not be properly installed or running in your machine. This is outside Polly's scope, so I can't help on this.
