Question mark on Remote Login gives no feedback

[Alan Pope 🍺🐧🐱 🦄]

Having never used the "Remote login" option in Lightdm before I thought I'd click the help (?) icon there. I then got a dialog offering a "set-up" option which I chose.
The logon section moved up to show the guest session login.
It then felt like my machine locked up. It's a core i7 with 8GB RAM and an SSD
I was about to reboot my laptop thinking it had crashed or locked up when eventually a desktop + browser appeared.

Perhaps we should provide some feedback or indicate in the "Set-up" dialog that we're going to take a while to spawn a guest session?
