Some users mentioned problems with the python add-on for fvdw-sl firmware.
It seems that the latest kernel upgrades are the cause.
In the add-ons download topic you can now download a new add-on. Besides python 2.7.3 it also contains setuptools for python (pip version 1.2.1) to be used to install python applications and furthermore also flexget (version 1.1.3)
With flexget we probably will do more in future
