[wxPython-users] Re: process stream CanRead() segfaults

[Brendan Simon]

Well I don't know if it actually does return a wxString.  Certainly the 
wx docs say that it does but I'm sure that's referring to the C++ 
framework rather than the python port.  All I know is that the exact 
same command (ls -l /tmp) works perfectly using demo.py and does not 
work in my code.  The only difference I can see is that I set the 
command directly with a python string in wxExecute, rather than the 
return object from wxTextCtrl.
