This helps for non-US languages, which otherwise traceback.
Fixes #140

I tested this and it works in both python2 and python3.

[nir0s]

Can we actually add a test for that?

Unfortunately I'm not able to run your tests. It hard assume python2.6, while I have python2.7. When I run tox I get:

$ tox

If you want to test it yourself, then

mv /usr/bin/lsb_release /usr/bin/lsb_release.bak
echo <<EOF > /usr/bin/lsb_release
#!/usr/bin/bash
echo žížíá
exit 7
EOF
chmod a+x /usr/bin/lsb_release

and try to import distro module.

Would it be possible to get a release with this fix in it?
