Qt visualization windows are not being released properly

What steps will reproduce the problem? 1. run attached file using "python trepHelloWorld.py" What is the expected output? What do you see instead? File should produce two identical, empty trep 3D visualization windows. Instead, after the destruction of first window, there are many GTK warnings printed to terminal, and the second window ends up being decorated with GTK instead of Qt. This ends up producing segmentation faults when running simulations with multiple visualizations in IPython (although they can be worked around by passing "--gui=qt" to IPython invocation).

Beyond IPython issues, one expects all visualization windows to be rendered identically. Please use labels and text to provide additional information.

Cannot reproduce it on Arch with python 2.7.5, ipython 0.13.2, pyqt 4.10.1, py-opengl 3.0.2. qt4 is 4.8.4 and latest version of trep.
