I think I did not see your first self-reply when I first replied.
If you think you are affected by this problem, have you checked your apps against this list?
So you currently have no /etc/hosts at all?
What I meant is: restore it to the installation default.
I think it should contain at least these two lines at the top:
127.0.0.1 localhost.localdomain localhost
::1 ip6-localhost localhost6.localdomain6 localhost6
OTOH, I just tested removing it and it has no effect on the browser.
I wonder how you installed, used and possibly removed that python library.
Re your journal output:
Yes, these lines seem relevant:

This is from a launcher start, yes?
Please compare to a cmdline start, and do the same with some other problematic apps as well.
