For now, the only workaround I found to start QGis is to remove 
completely my system-wide "c:\python" directory.
Trying to configure path and PYTHONPATH with priority to the QGis folder 
(such as the included .bat files do) does not work. Doing so, and using 
SysInternals Process Monitor, we can see it still tries to load things 
from my "c:\python" directory, and it fails because there are 
incompatible library versions.

Of course, removing my system-wide Python installation is not an 
acceptable workaround ;-)

How to force QGis to use only the Python stuff in its folders and 
sub-folders ? Virtualenv ?
