If you "hacked" a system, I would assume the first thing you'd do is patch any of your own known exploits, and others, so you don't lose ownership to some other hacker, right?
Wild! Mine crashed the first try, turned off Safari Suggestions, crash behavior gone.
Turned it back on... still no crash. Search engine makes no difference.
Wonder if it's a cache thing and disabling Suggestions cleared that, removing whatever bad data was hanging around, or if it was a purely server-side bug and they've already fixed it.
[EDIT] Some others saying it stopped happening, so may have been fixed.
