Does anyone have a fix for this? We have the same problem - external RSS
feeds work, but we can't display any Sharepoint RSS feeds with the webpart.
We are using MOSS 2007 RTM, with a basic install. The error we get is:

Exception in RssAggregatorWebPart::OnPreRender...
System.Collections.Generic.KeyNotFoundException: The given key was not
present in the dictionary. at
System.ThrowHelper.ThrowKeyNotFoundException() at
System.Collections.Generic.Dictionary`2.get_Item(TKey key) at
Microsoft.SharePoint.Portal.WebControls.RSSAggregatorWebPart.OnPreRender(EventArgs e)

Hi Kevin,

I had the same problem and found out that you can/have to use the Content
Query Webpart for internal feeds.

Regards,
Ute

Ute,

Thanks. We want to place an RSS feed of our CEOs blog on the main page of
the portal. From my understanding, My Site is a top-level site, so CQWP
can't see it.

In my opinion, this is a pretty significant limitation. I hope it gets
resolved.

Kevin
