Public bug reported: Ever since upgrading to 16.04, Rhythmbox GUI fails to open. Also, if I open User accounts under System Settings nothing opens, but after I can't close the System Settings window..
And here's a sample of auth.log entries: May 6 07:32:03 steven-OptiPlex-7020 lightdm: PAM unable to dlopen(pam_kwallet.so): /lib/security/pam_kwallet.so: cannot open shared object file: No such file or directory May 6 07:32:03 steven-OptiPlex-7020 lightdm: PAM adding faulty module: pam_kwallet.so May 6 07:32:03 steven-OptiPlex-7020 lightdm: PAM unable to dlopen(pam_kwallet5.so): /lib/security/pam_kwallet5.so: cannot open shared object file: No such file or directory May 6 07:32:03 steven-OptiPlex-7020 lightdm: PAM adding faulty module: pam_kwallet5.so May 6 07:32:03 steven-OptiPlex-7020 lightdm: pam_unix(lightdm-greeter:session): session opened for user lightdm by (uid=0) May 6 07:32:03 steven-OptiPlex-7020 systemd-logind[1004]: New session c1 of user lightdm.
