Lots more testing went on.  I now have good log output which I've attached to 
https://bugzilla.redhat.com/show_bug.cgi?id=472248  Meanwhile, my logwatch 
report has come in.  Could these entries have any bearing?

    kdm: :0: PAM adding faulty module: /lib/security/pam_gnome_keyring.so: 6 
Time(s)
    kdm: :0: PAM unable to dlopen(/lib/security/pam_gnome_keyring.so): 
/lib/security/pam_gnome_keyring.so: cannot open shared object file: No such 
file or directory: 6 Time(s)

Certainly gnome-keyring is used by NetworkManager.  If it's likely to be 
involved, I'll add this output to the bug report.
