You are right, I expected that gtk.DragContext would have an accesor
as well as a setter.

I'm ok with the concept of a single-line description of a clipping
living in the model, but the _MAX_DESCRIPTION_LENGTH value seems to me
like a UI decision. What about moving it to be an argument of

+            if key == 'STRING':

I'm not sure all text clippings will have the STRING target, I would do instead:

+            if key in ['STRING', 'text/plain', ...]:

(I'm not really sure which are the most common targets that contain
text, I would check the logs after a paste, these are printed in
