To debug your desktop application, why do you want to use any of the
tools from the SDK? You can just use the system's tools (e.g.
/usr/bin/python with no PYTHONHOME set)?

To do that, just start a new console, do *not* source the
/opt/poky/1.4.2/environment-* file. This should give you an empty
PYTHONHOME variable and an unmodified PATH, so you can just use the
regular tools on the desktop.
