Automatic redirect not working for 'download' action

• Display attachments from a particular page. For example the HTML code is like this

  <img alt="XWiki.org" class="icon" src="/xwiki/bin/download/XWiki/XWikiOrg/org.png">
  

• Now add a redirect XWiki.RedirectClass object from XWiki.XWikiOrg to NewPage1.NewPage2.WebHome
• The image will be broken with this message

  xwiki/bin/download/NewPage1/NewPage2/WebHome 404 (Not Found)

The problem is that the 'download' action doesn't construct correctly the URL, the last part (attachment name 'org.png') is not added in order to resolve.

Another example:

<img src="/xwiki/bin/download/XWiki/XWikiOrg/org.png?width=120" width="120" alt="XWiki.org">

will transform in

/xwiki/bin/download/NewPage1/NewPage2/WebHome?width=120
