I found a problem apparently related to string handling on MacOS X 
10.5/ppc with Python3 - not a new one though, at least it seemed to 
be present with 1.6.0b2:

All the previous failures on ppc are gone now, and with Python2.[4567] all tests are passing!
On Intel MacOS X (10.5/i386 and 10.6/x86_64) everything is OK for Python 2.5-3.2 as well.

Cheers,
