HI,
When using Safari 4.0.4 on OSX
10.6.3 ????????
It's not a bug... do maintenance.
From the Safari Menu Bar, click Safari / Empty Cache. When you are done with that...
From the Safari Menu Bar, click Safari / Reset Safari. Select the top 5 buttons and click Reset.
Go here for trouble shooting 3rd party plugins or input managers which might be causing the problem.

Third party software has caused issues for others with the scroll bar issue...

Since you are running Snow Leopard make sure Safari is running in 32-bit mode, not 64. Right or control click the Safari icon in the Applications folder, then click: Get Info In the Get Info window click the black disclosure triangle next to General so it faces down. Select 32 bit mode. Also, (in that same window) make sure Safari is NOT running in Rosetta.

Most web pages now include a small icon or 'favicon' which is visible in the address bar and next to bookmarks. With the vast amount of websites available over the internet, it is obvious that these icons can potentially take up a fair amount hard disk space. This will cause slow downs due to Safari having to 'sift' through the collection to find the right image. It is possible to erase the icons from your computer and start fresh.
*To delete Safari's icon cache using the Finder, open your user folder, navigate to ~/Library/Safari/ and move this file "webpageIcons.db to the Trash*
Clear Google History...
1. Go to the Safari Menu
2. Select Preferences
3. Select Autofill tab
4. Select the Edit button from the Other Forms Line
5. From the AutoFill list of sites select Google.com
6. Select Remove
7. Select Done
Relaunch Safari.
