Okay . . . I figured out the problem but not the fix.

The problem is: I installed some packages with pip, and python is
prepending ~/.local/lib/python2.7/site-packages paths to PYTHONPATH even
when I rewrite the that path in the shell.

So if I temporarily rename ~/.local/lib/python2.7/site-packages to
something else, the programmable filter works as expected.

Any idea how to best handle this?
