Comment 1 for bug 1646291

To test

Create a site with at least 1 non-admin user, masquerade as them and set a profile picture.

Then go to you dataroot and find the profileicon under artefacts/file/profileicons/originals as delete the icon

In Ubuntu you can go: sudo -i nautilus
to open up a gui with permissions to view files in your dataroot making the finding of the file easier.

Without patch:
When you reload the page you should get a broken image

With patch:
When you reload the page you should get the default human outline icon
