Not an in-range integer, float, or cons of integers

[Gian Uberto Lauri]

Hello!

I have a dual heading setup, and it happens that when I try to drag
and drop a file from the Eclipse navigator to Emacs moving from one to
the other screen, I get the message:

x-dnd-handle-xdnd: Not an in-range integer, float, or cons of integers

and the DND fails. What can I do to solve this problem?
