[Evolution] Missing attachment clip icon

[Andrea Vai <andrea vai unipv it>]

Hi,
  I have received a message with attachments, but the message list
doesn't show the clip icon.

The message is in an IMAP folder, and if I move/copy it to another
IMAP folder, the icon does not appear. On the other hand, if I
move/copy it to a local folder, the icon appears. If I copy/move it
from the local folder back to an IMAP folder, the icon does not
disappear.

I had a similar problem in the past [1], and Milan in comment #5 gave
me some instructions to track it down. The message comes from an Apple
Mail client, and the same was in [1]. Please let me know, if I can
help, what would be the best way to sort it out now.

Running evolution 3.26.6 on Fedora 27 (3.26.6-1.fc27)

Thank you,
Andrea
