[omniORB] ORB_init returns None (Python)

[Scott Robertson]

How are you importing ORB_init?

Are you importing it like:

from omniORB.CORBA import ORB_init

or are you importing

from CORBA import ORB_init?

Sometimes I've run into the case where I've imported the CORBA module
and ended up with the one from Orbit (part of the gnome package). Just a
shot in the dark, but maybe you're getting the wrong library.
