pre-set PYTHONPATH breaks major upgrade

Bug Description

Binary package hint: update-manager

This may actually be an underlying cause of several other bugs, but I'm not in a position to investigate, so...

The problem is that if you use update-manager to do an upgrade (in my case) from Gutsy to Hardy *and* you have PYTHONPATH set to use a library (even a local one) for the previous python version (2.5 in my case), necessary python modules will fail to load and the installation will break. Doing the installation with PYTHONPATH unset, everything works fine.

I might suggest the solution would be for update-manager to run python with the "-E" option to ignore any environment variable settings.

This ticket is tagged gutsy2hardy, an upgrade path that is no longer supported. Is there still anything left that needs to be done in a later release?
