It might be a bug, or it might be broken somehow on your machine. I can't reproduce this right now because I don't have Python 3 versions of all the libraries needed to run IPython in Python 3.
Can you see if preview(Integral(sqrt(1/x), x), output='png', viewer='file', filename='test.png') works for you? It should create a file called test.png in your current directory.
