There are many discussions here about this issue and how to fix it. The most important thing you can do is to make sure all your "Home" links point to the simple domain root, ending with a final slash. That is:
<a href="http:www.example.com/">Home</a>
In addition you may want to check out this thread:
Merging www.example.com/ and www.example.com/index.htm [webmasterworld.com]
You are lucky . Google has got the PR on the right one. Now make sure that every page of the site links back to http://www.domain.com/ in exactly that format, before Google changes its mind.
While you are there, get a site-wide 301 redirect from non-www to www installed too.
RewriteCond %{THE_REQUEST} ^.*\/index\.php
RewriteRule ^(.*)index\.php$ [yourdomain.com...] [R=301,L]
option.. it works a treat ...
