Right, there were several issues with the packaging on the Ubuntu
derivatives prior to 8.10 (intrepid).

https://bugs.launchpad.net/ubuntu/+source/zeroc-ice-python/+bug/213508

which basically required installing from source. If it's possible, you
might try upgrading.

Do you mind telling us how you installed Ice 3.3? Perhaps there are
issues with the installation. If it helps, I only have two packages
installed on Ubuntu 8.10:

dpkg -l | grep zeroc
ii  libzeroc-ice33   -- 3.3.0-5 -- Ice for C++ runtime library
ii  python-zeroc-ice -- 3.3.0-5 -- Ice for Python libraries

You don't need any of the jars since those are present in the
omero/lib/repository directory. For the build, if you have:

$ slice2py -v
3.3.0
$ slice2java -v
3.3.0

then things should completely normally.

Are you working from trunk or from Beta3.1? If you are working from
Beta3.1 then you will need to use the omero.sys.Parameters (no "I")
object directly. The "util" in the above is a typo that I'll fix in
the documentation. From trunk, you can see ParametersI in action at:

https://trac.openmicroscopy.org.uk/omero/browser/trunk/components/tools/OmeroPy/test/t_parameters.py

The problem here also looks like a mismatch between the Ice
versions. Since the classpath is automatically handled, my guess is
that slice2java and slice2py still point to 3.2.1 versions. If not,
let me know and we'll do some more tracking.

Definitely. Good luck,
