Exceptions from some URLs

Exceptions from some URLsSome of my old URLs yield exceptions when redirected to Community Server. If you search Google for "<A href="http://www.google.com/search?hl=en&lr=&q=joel+chen+exceptions&btnG=Search">Joel Chen Exceptions</A>" you get a link to <A HREF="/dottext/posts/148.aspx">this page</A>, which yields an exception. But if you search for "<A href="http://www.google.com/search?hl=en&lr=&q=c%23+sprintf&btnG=Search">C# sprintf</A>", which is the most popular way that people find my site, you get a link to <A HREF="/dottext/articles/158.aspx">this article</A>, which works fine.
