Example url:
http://www.facebook.com/sharer/sharer.php?u=http%3A%2F%2Fwww.rugbydump.com%2F2011%2F09%2F2124%2Frugby-world-cup-daily-tonga-beat-japan&src=sp
That's what's generated by the Share JS. If you visit the link (after decoding):
[...].com/2011/09/2124/rugby-world-cup-daily-tonga-beat-japan
You can view source and see open graph meta tags.
If the share url is changed to:
[...].com%2F2011%2F09%2F2124%2Frugby-world-cup-daily-tonga-beat-japan2&src=sp
(Adding a 2 to the end of the url) the result is fine. Likewise with other posts:
http://www.facebook.com/sharer/sharer.php?u=http%3A%2F%2Fwww.rugbydump.com%2F2011%2F09%2F2119%2Frugby-world-cup-daily-christchurch-revisted&src=sp
So all I'm getting is "Error" with no way of knowing what went wrong.
Any insight would be great. A thought was that the url was flagged or banned by FB but no way to tell.
[...] is used cause I can't use more than 2 urls.

I re-linted your URL in the Facebook developer debug page:
http://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fwww.rugbydump.com%2F2011%2F09%2F2124%2Frugby-world-cup-daily-tonga-beat-japan%2F
and it appears to work fine now. Facebook caches the data obtained from a page, so it's likely they hit your page during a period in which it had an error message instead of the usual contents.
