Summary: Class Problem with repr and getattr on PY2.3.2
Initial Comment:
Python 2.3.2 (#49, Oct 2 2003, 20:02:00) [MSC v.1200
32 bit (Intel)] on win32
IDLE 1.0
>>> class A:
def __init__(self): self.x=1
def __repr__(self): return "REPR"
def __getattr__(self,name): return "GETATTR"
>>> a=A()
>>> a
REPR
>>> print a
Traceback (most recent call last):
File "<pyshell#24>", line 1, in -toplevel-
print a
TypeError: 'str' object is not callable
>>> if a: print 1

Everything works fine without the __getattr__ code.

you're returning a string in response to a request for
__str__ and (I'd guess) __nonzero__.
Don't do that, raise AttributeError instead.
