Steps to reproduce:

1. Work with this file normally, edit the metadata, create new shapes. Save. Confirm it's still working.
2. Go back into the document properties > Licenses
3. Add a license. (if still responsive, go to next step)
4. Select the box tool and draw a box.

At this point, Inkscape has probably locked up.
