The idea is rather to try to solve any errors concerning wxPython 3 as 
it is more and more becoming the default in Linux distributions. Anna 
has been quite active in trying to solve any specific wxPython3 issues.

On my Debian Testing system I have Python 2.7.8 and wxPython: 
and I do not see your error. So it would be interesting to explore what 
happens on your system. What graphical environment are you running in ? 
What does 'echo $SESSION_MANAGER' in a terminal give you ?
