How do I handle trailing .. on url?

How do I handle atrailing .. appended on this url? All other redirects are working with various rules and maps. This one gives error.

http://www.realestate-bigbear.com/PageManager/Default.aspx/PageID=2038061..

However, the redirect for the "clean" url works great:

 http://www.realestate-bigbear.com/PageManager/Default.aspx/PageID=2038061

Here is the rule:

<rulename="PM Static Redirects"stopProcessing="true"><matchurl="^PageManager/Default\.aspx/PageID=([0-9]+)"ignoreCase="true"/><conditions><addinput="{PageManagerRedirects:{R:1}}"pattern="(.+)"/></conditions><actiontype="Redirect"redirectType="Permanent"appendQueryString="false"url="http://www.realestate-bigbear.com/{C:1}"/></rule>
