Fatal Python error: Could not import CORBA

[jeffl <jeffl defcen gov au>]

I have this error when running utilities such as hwbrowser, up2date, 
internet -druid etc. eg.

>hwbrowser
Fatal Python error: Could not import CORBA
/usr/share/hwbrowser/hwbrowser: line 4: 22715 Aborted 
/usr/bin/python /usr/share/hwbrowser/DeviceList.py

Other Corba functions (Gnome bits and pieces, Evolution etc) seem to 
work but not these RH ones.  I think it looks like a config problem but 
there is no info on how these things are set up.  Can anyone help.
