I am not sure how you have managed to downgrade that far to when there
were no GNB classifier in PyMVPA yet -- was introduced in 0.4.4.

I totally understand your concerns about upgrades whenever you are in
the middle of the analysis, but 0.4.3 is quite an old version and we
tried to keep 0.4.x post 0.4.3 primarily for bugfixes, so I do not
expect much of unexpected functionality changes, besides few additional
enhancements (such as GNB).  Thus you are advised to upgrade from 0.4.3
;)

you could try it easily by building it from GIT source and seeing what
effect it has on your analysis scripts:

sudo apt-get update
sudo apt-get install git-core
git clone git://github.com/PyMVPA/PyMVPA.git
cd PyMVPA
git checkout --track origin/maint/0.4
make
export PYTHONPATH=$PWD

and then cd to wherever you need to run your scripts to see if they
behave the same way
