Safari 8.0 crashes when a website is opened

[scootermafia]

Mountain Lion GM is installed, upgrade install (yeah, I know). I've cleaned every possible cache, etc. The problem happens on the guest account too. Here is the crash log. I can open Safari and look at preference menus, etc but going to any site makes the site start to open then it immediately crashes. I shortened the crash log a bit.

Looking at the crash log, it looks like you have a plugin called SafariStand. Uninstall it and see if Safari works again.

I searched SafariStand on google and it looks like it changes some behavior of Safari and that might be interfering with it. Check that you don't have anything under ~/Library/Application Support/SIMBL/Plugins/

Delete it if you do

That totally just fixed the problem. I don't know how I didn't see the "stand" menu that was present in Safari. Somehow with Safaristand I completely forgot I even had it (it never showed itself when I had Lion installed, it was just lurking in the background and materialized with the ML install) so it was active. If anyone else gets Safari weirdness, go to library/application support/SIMBL/plugins and delete everything in there to fix this issue.
