Yes, that makes it work within nautilus!
Thank you.

Unfortunately, somehow add-channel within miro is still not working.
It spawns the link in the chosen browser (epiphany in my case), afterwhich i have to manually double-click it.
But at least that part works now. I'll go look at how miro (which uses xul and gecko) figures out the mime-type.
