There is a bug in Python's uuid module that has been affecting official Blender releases on Windows for several years. It's triggered by Blender's inclusion of the CRT redistributables, and causes a runtime exception to be thrown when the module is first imported. It's harmless, but the OS "runtime error" window that appears is disconcerting for users and a thorn in the side of anyone whose addon uses uuid.
InI've applied the fix suggested in Python's bug tracker, and it works just fine. It would be good to get it into the next Blender release.
The file is located at lib/*/release/python33.tar.gz/uuid.py. I don't know how Git would handle changes to that file...perhaps a "patches" subdir and change to the INSTALL project would be appropriate?
