Today I also run into the same error wile installing Cinnamon on my laptop. I'm not sure what the error messages mean and how to solve them:
Module 'Clutter' imported with conflicting versions '1.0' and '0'
error parsing file Cinnamon-0.1.gir: Failed to parse included gir Meta-Muffin.0
Has someone a hint or idea how to fix this problem and could assist in getting Cinnamon installed?
Thanks a lot
