I do get the segfault with Python 2.0 on FreeBSD:

[chapmanb]$ uname -a
FreeBSD insomniac.athen1.ga.home.com 4.3-STABLE FreeBSD 4.3-STABLE #5: Fri Jun

>>> from Bio import Seq
>>> l = Seq.MutableSeq('ACDEFG')            
>>> print l
MutableSeq('ACDEFG', Alphabet())
>>> l
Segmentation fault (core dumped)

but I don't see it with NetBSD/Python2.1:

[chapmanb]$ uname -a

I'd suspect this is a tricky bug in 2.0 that got fixed somewhere along
the line in 2.1.
