Hi, I am trying to fix an issue, I found coming up with PR#916<https://github.com/scikit-image/scikit-image/pull/916> I am trying to use scikit-learn original build in master (0.10dev) with Python 3.3. When I use *img = novice.open(<image path or URL>)*, I am getting an error http://pastebin.com/F1BXwRCH. I noticed that *skimage.io.imread(<image path>)* returns None on 0.10dev. I also tried to setup a fresh virtual environment but I am facing the same problem. When I use the same original build in master with Python 2.7, it works fine. Any help is appreciated.
