Can't connect through SSH with Files to another Freya computer

I've just reinstalled Freya on a computer that was previously on Xubuntu. Current setup is the following:
1) laptop on Freya
2) desktop PC on Freya named conurb (zeroconf name: conurb.local) − that's the one that was previously on Xubuntu

On the desktop PC, I've installed openssh-server.

Previously, I could connect through SSH with Files from the laptop (1) to the desktop PC (2) using its zeroconf name with no problem. Now that(2) is on Freya too:
- pinging conurb.local works, so zeroconf seems to work correctly
- connecting through SSH in a shell from (1) to (2) as conurb.local works
- connecting through SSH in Files from (1) to (2) when using its local IP of the machine works
- connecting through SSH in Files from (1) to (2) when using its zeroconf name (conurb.local) doesn't work and ends with a timeout

Of course, I've revoked the previous SSH keys from the known hosts on the laptop.

That's pretty strange, given that the same setup worked fine when the desktop PC was on Xubuntu. Might be related to the other network issues I've reported, though I don't understand how as it's the server that changed.

Can anybody reproduce the bug?
