The solutions here did not work in my case, but a solution which did work for me can be found in https://bugs.launchpad.net/ubuntu/+source/gnome-keyring/+bug/1022322 which says:
The file causing the problem is /etc/xdg/autostart/gnome-keyring-pkcs11.desktop . The line OnlyShowIn=GNOME;Unity should be changed to OnlyShowIn=GNOME;Unity;XFCE
There are similar statements above, but none include XFCE.
