Can't open Safari in OSX 10.7.2

[Cripps]

Get this error message when trying to launch Safari:

"Safari cannot be opened because of a problem".

I am not clever enough to know what to do next.

Problem Details and System Configuration shows:
Dyld Error Message:
Symbol not found: __ZN7WebCore14ScrollableArea24setScrollbarOverlayStyleENS_21ScrollbarOverlayStyleE
Referenced from: /System/Library/PrivateFrameworks/WebKit2.framework/Versions/A/WebKit2

in /System/Library/PrivateFrameworks/WebKit2.framework/Versions/A/WebKit2

Thanks for any advice.

Re-download Safari from Apple's site, then test. After (not before!!!) you have resolved the issue run Software Update and get 10.7.3.
