Comment 28 for bug 885492

Found a 100% working fix:

"1) Install getlibs

wget https://launchpad.net/~jcollins/+archive/jaminppa/+build/1482994/+files/getlibs_2.06-0ubuntu1%7Eppa2_all.deb

sudo dpkg -i getlibs_2.06-0ubuntu1~ppa2_all.deb

2) Install the 32bit lib

getlibs -p gnome-keyring:i386

3) Make the symbolic link

sudo ln -s /usr/lib32/i386-linux-gnu/pkcs11/gnome-keyring-pkcs11.so /usr/lib/i386-linux-gnu/pkcs11/gnome-keyring-pkcs11.so

Now run your Crossover/Wine app and the error is gone."
