I recall seeing this before, it should be fixed in 2.8.x, but I cannot
completely promise that it is.

The problem is that gtk.FileChooserEntry, which is a private widget of
gtk.FileChooserEntry is a sbuclass of gtk.Entry (which implements
gtk.Editable) and reimplements gtk.Editable itself.

Gustavo, do you remember this being fixed or not?
