Created attachment 1941769 [details]
proxy dialog with filled fields

I want to register a system using initial-setup-graphical app.
I want to use auth proxy.

see details of that case: https://polarion.engineering.redhat.com/polarion/redirect/project/RHELSS/workitem?id=RHEL7-19999

in a terminal at desktop enable root access to the display:

xhost si:localuser:root

in a terminal do:
ssh root@$HOST
export DISPLAY:0
/usr/libexec/initial-setup/initial-setup-graphical

Click on 'Subscription Manager'
Click on 'Configure Proxy' button
Check a checkbox 'I would like to connect via an HTTP Proxy'
Fill a field 'Proxy Location' by an url to auth proxy 
..note: no username or password is filled
Click on a button 'Test Connection'

Wait a little.
The button returns into an unclicked state after a while and no error message does appear.

A long traceback appears on a terminal where initial-setup-graphical is run.
see below.

The graphical app gets frozen and I cannot click on any GUI element. I have to reboot the system.
