Summary: Generators produce wrong exception

Initial Comment:
The following script :

def f():
    yield "%s" %('Et','to')
    
for i in f(): print i

will produce the following traceback in Python 2.3.4

Traceback (most recent call last):
  File "python_generator_bug.py", line 6, in ?
    b+=f()
TypeError: argument to += must be iterable

Where I would expect a:

TypeError : not all arguments converted during string 
formatting.
