Remmina appears to have had total amnesia that it supports RDP. When I try to launch an rdp session from my list of saved hosts, I get a popup that says "Install the RDP protocol plugin first." However, RDP is not on the list of available plugins. (And should definitely be installed, as I've been using it...)
Not what you want to discover when you go to login in to work from home on a Monday morning! :-P
