after updating from freerdp version 2.1.1 to version 2.1.2, I immediately
noticed constant disconnects.
I use Remmina as a frontend, which automatically tries to reconnect to the
remote host, after a disconnect happens.
This results in the following scenario:

I successfully connect to a remote host
I try to open a folder on the desktop of the remote host (or do any other
action such as opening the "start-menu")
freerdp disconnects
remmina shows a black screen saying that it will try to reconnect
freerdp reconnects
I try the next action on the remote host
freerdp disconnects again
and so on...
