The following snippet demonstrates the problem:

-------------------------------------
class Test(object):
    def get(self):
        print "get"
    def set(self, v):
        print "set"
    test = property(get, set)

t = Test()
t.test
t.test = 3
-----------------------------------

"get" is printed twice (expected once?), "set" is printed only once (as
expected)

Tried your snippet with both py2.5 and py2.6.  It works as expected (one
get and one set).

Right you are. Looks like its actually an IPython specific behaviour
here (didn't think to check that in the first place, sorry).
