Py3.0b2. This bug seems to be quite annoying. Especially when one works
with a main module importing modules which are importing modules and so
on, all modules having an encoding declaration. The Traceback (and the
user) is (are) a little bit lost.

---------
# -*- coding: cp1252 -*-
# modb.py

def fb():
    i = 1
    j = 0
    r =  i / j    
-----------
# -*- coding: cp1252 -*-
# moda.py

import modb

def fa():
    modb.fb()
-----------
# -*- coding: cp1252 -*-
# main.py

import moda

def main():
    moda.fa()

if __name__ == '__main__':
    main()
-----------

Running main.py leads to an
