Fixed in trunk, which is now held in bzr, as you may have seen from
recent discussions:

http://bazaar.launchpad.net/~ipython/ipython/stable-dev/revision/45

You can get the log and the command to download from here:

https://code.launchpad.net/~ipython/ipython/stable-dev

Let me know if you have any issues updating to bzr and I'll cut a build for you.

Take care,
