Benjamin, what you're seeing appears to be bug #1607535. (That bug report doesn't quote the "/the fonts/" URL directly, but it links to a comment that does.
I have a bug report (bug #1575408) against ttf-mscorefonts-installer due to the "Can't drop privileges" warning, but am assuming that that was a specific instance of the more general bug described here, and so have marked my bug as a duplicate of this one.
