Safari opens but crashes when loading any page

I recently upgraded to Safari 6.0 (7536.25) on Lion 10.7.4. Now Safari opens but crashes as soon as I try to load a page. I've tried most of the fixes that I could find in the recent posts:

• different pages to be sure it isn't page specific
• disabled all extensions
• renamed the extension folder so it wouldn't be accessible (even though all were disabled)

  I noticed that Safari recreated the folder still with all extensions disabled but just in case I clicked the Off switch at the top of the Extension list

• renamed cache.db to get a new one
• renamed webpageicons.db
• Reinstalled Safari from the link in one of the forum posts

Please help!
