Comment 4 for bug 306185

Same - reproducible on an up to date system as of this message in jaunty....

Tracking it down there appears to be a search path issue for the module...

Following the instructions for freevo here:

http://ubuntuforums.org/archive/index.php/t-731013.html

Which had a similar issue results in a working system...

Specifically:

cd /usr/lib/python2.5/site-packages/
sudo ln -s oldxml/_xmlplus/

So this is probably a python-xml issue (and other modules that now install in oldxml/_xmlplus will probably be the same) where either the sys.path default path needs fixing or this symlink in place by default.

After putting the symlink in place I was able to use hb_gui as per intrepid - at least from initial testing.
