Thanks for the fix.

However, without a test I will not be able to merge it in.
Please use nosetest to run the existing tests. You could add a new one which verifies your fix.

Thank you

The problem was that the tests didn't run on my machine, otherwise I would add the tests as well. Take a look at my previous comment on this: #41 (comment)

I do not remember what was the problem, I have never worked with nose before. But let me take a look again. ;-)

Thank you !
I believe your fix is already implemented by now.
