RDP crashes Virtualbox guest [DoS]

Hello, I'm trying to enable external authentications but every time I try to connect to the guest screen, I find myself disconnected and the Virtal-guest crashes. If I enabled this in the internet, anyone can disable my access to my virtual-guests. I found someone has the same bug in the earlier release 2.x, but it seems everyone has ignored him.
Here is my log.
