I describe how attributes defined as properties raise
inconsistent errors depending on whether the property
is defined in C or Python.  By default in C, you'll get
a TypeError while in Python you'll get an AttributeError.

I think both should raise AttributeErrors. Here is a
patch against Python 2.4 which should be ported to 2.5
(and possibly 2.3 if we care).

Well, I was going to attach a patch, but it seems SF is
borked and won't let me upload anything (yes the stupid
checkbox was checked).  The patch is simple though: change
PyExc_TypeError to PyExc_AttributeError on lines 147 and 202
in Objects/descrobject.c (rev 2.38)

The change is in 2.5 and will /not/ be backported to 2.4.
