Comment 9 for bug 1285746

Btw, I've noticed, that seahorse and GNOME Shell in Ubuntu 14.04 (Trusty) with lightdm crashes if you enter a blank password in Seahorse keyring password changing dialog.
But crash doesn't appear when lightdm is removed and gdm is used instead, that's why keyring password dialog in Chromium web browser after automatic login setup can be dismissed by instaling gdm and purging lightdm :)
