But the second one works fine -- so it's not really an issue that bothers me, but I thought it might interest some folks. Here's an IPython session that demonstrates the issue:

Python 2.6.2 (r262:71605, Apr 14 2009, 22:40:02) [MSC v.1500 32 bit (Intel)]

IPython 0.10 -- An enhanced Interactive Python.
