Designer for wxpython-phoenix won't work without adjustements

[scimax]

After running 2to3 I still can't get the designer working. I fixed the error

ImportError: No module named 'wx.gizmos'

coming from inspector.py, replacing the TreeListClass with the new one in wxPython. But when running

python -m tools.gui.designer

afterwards, python crashes.

System info:

• python 3.5.1
• wxPython-Phoenix (3.0.3.dev2824+3f01517)
• Windows 10 with MinGW/msys
