The PYTHONPATH environment variable which was set by omd and .profile for all processes in the site was confusing external Python based tools like for example gdb or the command not found helpers of Ubuntu. This resulted in confusing stack traces.

The PYTHONPATH needed to be set in previous versions to make the python environment know about the site specific python module paths (lib/python, local/lib/python). These paths are now set using standard mechanisms of python (lib/python2.7/sitecustomize.py).
