Send to button broken

How to reproduce

1. Right click a place on map
2. Press What’s here menu item
3. Click on Share location button
4. Click Send to… button

Nothing will happen and the following will be logged into console:

(org.gnome.Maps:570453): Gjs-CRITICAL **: 21:05:32.445: JS ERROR: TypeError: (intermediate value).URI is undefined

Maybe something to do with the fact that the UI file still requires GTK 3.12
