If you have Safari 5.1.6 installed, updating to Safari 6 may help. Confirm you have Safari 5.1.6 installed by right or control clicking the Safari app in the Applications folder then click Get Info. You'll see the version there.
If it's definitely 5.1.6, follow these instructions.

If you have a different version of Safari installed, post a crash report.
If Safari has just crashed, press the Report button on the CrashReporter dialog box to view the crash information.
Copy/paste the entire contents of the Crash Reporter window into your reply. If the crash report dialog does not appear or the crash is hard to reproduce, crash logs can be retrieved from the ~/Library/Logs/CrashReporter> folder.
