Hm, seems strange, a host that cannot resolve "localhost", what is the rational behind this in openSUSE?

IIRC the SESSION_MANAGER environment variable contained "localhost", so if session clients are unable to resolve "localhost", they will not be able to connect to the session manager. This might have changed in libSM/libICE since then (most probably, otherwise nothing would work on openSUSE).
