Forward as iCalendar: Embed event's local attachments
I create in Evolution an iCalendar object with attachment. Then I do the
Forward as iCalender… action (METHOD:PUBLISH). The received/sent email contains:
ATTACH;FILENAME=abc.jpg:file: ///home/d/.cache/evolution/calendar/5ee4cacf594245956bdd7ab7d212c3adafa2ad 00/88e6c18862d77667e540a429993f8ed0d4b8970f-abc.jpg
Instead, the email shall contain the file content (base64 encoded), unless the attachment is URI to some resource in Internet (Evolution cannot create the latter), and perhaps when CalDAV Managed Attachments are involved.
