UnicodeDecodeError when starting Ipython notebook on a directory containing a file with a non-ascii character

[germank]

Here's how to replicate this bug. First, I'm using the latest release (it happened with 1.0.0 as well):
$ ipython --version
1.1.0

Now, I create a file containing some weird character on it, for example the spanish letter "ñ":
$ cat > ñ.txt
^D

Finally, I try to start the Ipython notebook in that directory, and that's what happens:
$ ipython notebook
