can't connect to 2008r2 when set "negotiation" security mode

Created by: emoxam

In my ubuntu 13.04 and remmina 1.0.0-4ubuntu2 when i try to connect windows 2008 r2 server i get an error "can't connect to RDP server" (in Russian) so i learned it's setted up in "negotiation" security mode by default, if i choose RDP ot TLS i can connect.
