[Users] Calendar not accepting links

[Jerry]

I have been trying to get this link accepted into the Vcalendar
application:
<webcals://cid-8f3665f235766aff.calendar.live.com/calendar/private/26d04377-f571-4284-945f-fabd1ae84ed8/2d0443ed-3309-44fb-b977-54b3b3c930a1/calendar.ics>;
however, it keeps rejecting it with a "Could not parse the URL." error.
I have claws-mail version 3.9.2 installed on a FreeBSD-10 BETA3 amd64
system.
