Depending on where you got the extensions some are not compatible with 3.2 and will cause the system to lock on start-up as the worst I've seen.
Some extensions and themes only work with 3.0 and because of API changes in 3.2 they are not compatible. To fix it (aslong as you used sulpher) would be to uninstall them using "equo remove <the shell extensions you installed>". Or if you prefer to do it manually, you can look in /home/<username>/.local/share/gnome-shell/extensions and remove the directorys.
Also you can check /usr/share/gnome-shell/extensions (default for the shell extensions that are systemwide) these will have to be deleted with the "root" user account though.
The extensions that i can say do not cause issues (if they are the 3.2 ones) are the one from Entropy (I run them with a 9500GT nvidia on proprietary drivers).
Hope this helps a little.
