Post hotfix post-SP1 problem with DTS Designer

After I installed build 2153, my SQL Server Managment Studio DTS 2000 Package Designer (which is part of SQL Server 2005 Feature Pack) was not working.

After I searched for an updated feature pack (which has not been released) I discovered that the problem has been described in KB917406. May be there are other factors, because I installed other programs yesterday after the build 2153, anyway I think this post is a good reminder.
