Skip() allows the default event handler to still be run after your 
handler returns, so that avoids the Windows thing of resending the event 
if it thinks that it still needs painted.  IOW, it is probably just 
hiding the real problem, not solving it.  If you are creating a 
wx.PaintDC before the exception happens then I can think of two other 
things that could cause this.  1. The window you are passing to 
wx.PaintDC is not the one that the event was sent for.  2. You are 
calling Refresh.  If neither of these are true then you might want to 
try and reproduce this in a small sample app that doesn't use VTK.
