Recently upgraded 16.04 to 18.04.
In the Settings app, I navigate to Details, Users. I click the thumbnail for my user account's image.
I am able to select one of the predetermined images that appears, but if instead I click "Select a file", then in the ensuing dialog ("Browse for more pictures"), I can highlight a local image file, but the "Open" button in the header bar remains greyed out, so I cannot actually select an image.
Has anyone seen this behavior? Know how to fix it?
