New mac book pro, Safari a zombie process on launch?

My previous Mac book died, and I purchased a new one last week.

I started the restore of my data, which, mistakenly, included the Library directory in my User directory.

Now Safari will not launch, it starts up as Process not responding according to Activity Monitor.

I've tried deleting the .plist files as suggested by similar, older posts about such events, and looked for Caches, Metadata, and plug-ins which might be at fault, but to no avail.

I'm running OS X 10.8.2 with Safari 6.0.2 according to info on it from the apps directory.

It of course opens fine for other users on the same Mac. I've tried copying over the Library/Safari directory from a working account contents into my directory. Still no joy.

I'm stumped on how to remedy this. Short of creating a new account and moving all my data to it, is there anything else I should try?

Thanks for your time.
