Comment 14 for bug 287715

So what we really need to do here is to not create CK sessions for every system session like cron. It creates not only this bug, but has a couple of other side effects, like making system users appear in gdm, and showing them as "most popular login" in the gdm user list.

I discussed this with Steve Langasek, and he said that he plans to split "common-session", so that we will get a new /etc/pam.d/common-session-interactive. Then libpam-ck-connector could register there instead of to common-session.
