Can't parse ics URL when it has an "@" in it

Hi, I'm trying to fetch events from a Mobilizon group (https://mobilizon.infini.fr/@infini/feed/ics) but i get an error : //mobilizon.infini.fr/@infini/feed/ics, ics] Invalid email mailto:Infini

I think the @ in the URL is causing an issue. I works great for URLs without an @.

Thanks
