I really didn’t find anyone else reporting this issue.  I created a custom SiteMapProvider and it magically provided a breadcrumb for me.  Sweet!  Then I was demo’ing and no breadcrumb…

I discovered that deleting the trailing slash brought the breadcrumb back. 

I may have added my SiteMapNode urls incompatibly with the SiteMapProvider expectations.  But my urls are perfectly valid and "/my-specialurl" is the same as "/my-special-url/".  In my code, I’m stripping trailing slashes before comparison.  Shouldn’t the SiteMapProvider do the same?  Who knows?

Code change was easy:

(note: I edited this from the original post as I discovered that I overrode the less ideal signiture of this method, this covers both )

public override SiteMapNode FindSiteMapNode(string rawUrl)

{

    // base method doesn’t handle trailing slash very well

    SiteMapNode match = base.FindSiteMapNode( rawUrl );

    // base method worked!

    if( match != null ) return match;

    // try without trailing slash

    if( rawUrl.EndsWith( "/" ) ) match = base.FindSiteMapNode( rawUrl.Substring( 0, rawUrl.Length - 1 ) );

    return match;

}
