Hey Eloy,

You need to have snapd-xdg-open package installed on the desktop. IIRC,
the goal was to seed it by default or have snapd recommending it. CCing
mvo on that who also responsible for the package on ubuntu if there is
any reason this isn't the case yet.

Ensure you are then using xdg-open from /usr/local/bin/.

I konw this is working with the unity7 interface (I don't remember if
the x11 one is succifient, but it should, if not, it's a bug).
Cheers
Didier
