Can't start nm-applet -- keyring error

I installed wheezy a week ago (with the installer which includes xfce), and nm-applet was working fine. But today it won't start and gives the message: WARNING: gnome-keyring:: couldn't connect to: /home/tom/.cache/keyring-4LJPFc/pkcs11: No such file or directory ** Message: applet now removed
