Comment(by godiard):

 I was looking at this, found a few parts where we need to do changes due
 to gtk3 as  .target by .get_target() and .data by .get_data()

 The same happen with #3819 "Clipboard drag&drop: error when dragging an
 icon to the clipboard". The attached patch solve these issues, but does
 not solve the problem described in these ticket.

 I have tried changing the introspection without luck (and updated upstream
 ticket).

 The attached patch can drag a journal entry (if dragged from the date
 column) to the frame clipboard area. One item is created, but the data is
 broken. The list of target s have garbage too, and probably is the reason
 we can't drop over the volume buttons.
 This is the reason I was trying work with dnd in the clipboard and journal
 at the same time.

 Also I attached a dnd example using a treeview copied from
