    theme-adium: deal with g_resources_lookup_data() failing
    
    Only empathy-chat registers the gresources so when executing this code from
    the empathy process (theme preview in the preferences dialog) we don't find
    the resource. That's fine as this JS code is only used for the infinite
    callback but best to not warning.
