This should be fixed now; but all you really have access to immediately
is the owner's name until the first services provided by the owner (ie,
the chat and presence ones) are resolved.  Eventually you'll likely have
access to the owner's color and such before service resolution too.  So
you shouldn't need to import and/or init sugar.env.
