Pasting file with Ctrl+V in the editor does not append the file
I use Archlinux with Nautilus 3.36.2 and Evolution 3.36.2.
When I copy a file in Nautilus and paste it in the Evolution editor in the body part (either with right-click or with Ctrl+C and Ctrl+V), the following text appears:
x-special/nautilus-clipboard
copy
In previous versions (3.34, I guess), the same operation appended the file to the email. This was a very convenient way to attach files to emails.
