WLW WebException accessing Blogger posts

Blogger has according to Microsoft introduced a problem that shows itself this way within Windows Live Writer.
 

It happened when I used File>Open and changed from 25 to 50 or more items to select from.

System.Net.WebException: The remote server returned an error: (400) Bad Request.
   at System.Net.HttpWebRequest.GetResponse()
   at WindowsLive.Writer.BlogClient.Clients.RedirectHelper.GetResponse(String initialUri, RequestFactory requestFactory)

Microsoft are waiting for them to make a fix and unfortunately don’t have an ETA.

Update 2008-10-02 This problem has now been fixed.
