mcabber couldn't connect to tmp keyring file

[konrad]

After updating to 12.04 beta I get the following error when starting mcabber:

[11:07:43] Certificate is not trusted!
[11:07:43] Disconnected, reason: 3->'LM_DISCONNECT_REASON_ERROR'
WARNING: gnome-keyring:: couldn't connect to: /tmp/keyring-Jeqydj/pkcs11: No such file or directory

After that nothing else happens and mcabber does not connect to the XMMP server. There is a blog post reporting and showing a fix for the same error on ArchLinux:

Maybe this gives a hint for a solution.
