For the Force Close in Setup Wizard, no it's simply a bug. Just use WinSCP on computer or FileBox or any rooted file manager you want and go delete "SetupWizard.apk" under /home/system/app/. This will simply delete Setup Wizard and a reboot will take you directly to Launcher screen. Enjoy this not-so-fluid(-but-can-be-optimized to me) ICS experience!
