Wheezy/Xfce Gnome keyring problem

[Paul E Condon <pecondon@mesanetworks.net>]

I'm running Wheezy/Xfce in a fresh install. I went to Xfce because of
issues with Gnome3. The fresh install was done using a netinst CD that
is advertised as being specifically for installing Xfce, but it also
installs large chunks of Gnome. I purged the Gnome stuff after the
install was finished. But there is an annoying leftover of Gnome
(within CUPS? or Xfce? or other?):

When I print files using CUPS, I get a message:

p11-kit: couldn't load module: /usr/lib/i386-linux-gnu/pkcs11/gnome-keyring-pkcs11.so: /usr/lib/i386-linux-gnu/pkcs11/gnome-keyring-pkcs11.so: cannot open shared object file: No such file or directory

This message seems to be a warning, because CUPS prints the file
immediately and correctly. But I would like to remove or suppress this
message, and can't find directions for doing so. Where should I look?
Or is there a simple trick that I can be taught?

TIA

PS. I do use gnome-terminal as my favorite terminal emulator so gnome
is not truly and completely purged, but I know from what I report 
above that I don't really need the keyring part.
