I just tried to run the code hereunder with Python 2.6.5:

def main():
     raise "Abc"

main()

This is what I get :

Traceback (most recent call last):
   File "test.py", line 4, in <module>
     main()
   File "test.py", line 2, in main
     raise "Abc"
TypeError: exceptions must be old-style classes or derived from 
BaseException, not str

I am not sure what the documentation above means but it seems to be text 
that was not fixed...
