Comment 9 for bug 752282

I've made a fix in the python keyring.

https://bitbucket.org/kang/python-keyring-lib/pull-request/3/do-not-try-to-connect-to-the-gnome-keyring

I checked for DBUS_SESSION_BUS_ADDRESS, as Markus suggested, as well as DISPLAY. Benji did a bit of experimentation to show that it was possible to have the DBUS_SESSION_BUS_ADDRESS but not DISPLAY, and we believe that it is correct in that case to not try to work with the Gnome keyring.
