Sorry for the confusion:
I was looking at configuration of the wrong virtual host in my reverse
proxy. The virtual host actually used does *not* modify any security
headers like Content-Security-Policy.

Frankly I was not aware that Galène sets Content-Security-Policy. I will
look more closely into that. Nevertheless it's irrelevant for this
particular issue.

I definitely know that Safari users were successfully using the system
before upgrade to commit 9d9db1a92060a3e0ce15021234b8561a3e6bfc49.

Ciao, Michael.
