Sure, I agree.
I have never taken the Wizard approach as I find that building my own pages and using the behaviours provides a much more flexible development environment, but I can see where the wizards might be useful for people who aren't familiar with creating web pages etc.
I have to say that since the fix to the MAC CS6 issues the latest extensions do seem quite stable and this is the first error I have come across after building quite a comprehensive CMS and eCommerce solution.
