Safari crashing when displaying Top Sites after installing Yosemite

[sam.walker22]

After installing Yosemite, my Safari was crashing immediately after opening it.

Eventually I found this site (http://georgegarside.com/blog/how-to-fix-safari-8-crash-since-yosemite-dp4/) which explains about an issue with Safari since DP4 and was able to fix it following their instructions. (My homepage was set to Top Sites, which explains the immediate crashing).

It seems Yosemite developer preview 4 (DP4) has broken Safari 8’s favourites, or Smart Search Field, or something. Anyway, there’s a quick fix; run the following commands in Terminal:

defaults write com.apple.Safari ShowFavoritesUnderSmartSearchField 0
defaults write com.apple.Safari NewWindowBehavior 1
defaults write com.apple.Safari NewTabBehavior 1

This will hide the favourites from under the smart search field, which fixes the crash that occurs when you click on the address bar, as well as fixing the crash caused by showing the Top Sites page by changing the new window behaviour and new tab behaviour to about:blank.

You would have thought apple would have fixed this in the public release?
