I am having this problem, out of nowhere Safari 5.0 just quits on me and says "Safari Unexpectedly Quit" I have tried everything, deleting my prefs, no avail. I did not have this problem at all with Safari 4.0 or earlier versions. When I updated to 10.6.4 it automatically updated to Safari 5.0 even after I had reinstalled the older 4.0 from the Snow Leopard DVD. Anybody else having trouble with Safari 5.0 crashing? I mean it does this more than 10x per day! It's horrible!! I've started sending bug reports to Apple everytime it does this now, hopefully they can get this worked out in a 5.0.1 update.
Also I have duplicated the same problem on two machines. Happens on my MacBook Pro 2.4GHz 4GB RAM at home, and happens to a 2.26GHz Mac Mini at my workplace as well. Both 10.6.4 and Safari 5.0. Just quits unexpectedly constantly. When I restart the app, it WILL NOT access any website. I have to quit it again and restart the app again, to regain internet access. This is really annoying. Like I said, after the crash and the app reboots I don't have internet access on Safari. I have to manually quit and start again, and then it's OK.
