crash in wx.TreeListCtrl SelectItem()

Try anyway to reproduce with a sample. The only way I know in this case 
is to split the code and see if it happens again. If so, split again, 
and again, and so on...
It can be long, but the only way. Very often, you'll find yourself the 
buggy part.
Once time you'll have a sample, post it, I can try on linux and windows.
Also please give the versions of the softwares you use.
