@DavidRea: If you are still having the problem, post your crash report so we can see it. You can also create a new User account on your Mac and test for this problem with Safari there. If it happens there, it is a systemwide issue.
@Everyone else: The link to download the Flash uninstaller is

Do not try to install a version 9; only install the latest version, then Repair Disk Permissions and restart Safari to see if the problem continues. Your problems may be entirely different than the OP, so you should all start your own thread with details of your problem, along with what you've tried so far to resolve it, and the results. Continuing to post in this thread is threadjacking, and it will only lead to your problems being ignored in deference to the OP.
