if i try "sudo gdb /usr/bin/python2.7" and inside gdb "run /usr/bin/hp-setup -i", then it ends with : --------------------------------------------- You do not have permission to add a printer.

You should not need root to add a printer. Is the user running hp-setup in the lpadmin group?
Yes, my user is in lpadmin (and has always been). Whether I do "hp-setup" or "sudo hp-setup", i keep having the dialog "Enter Username/Password" at the end (clicking on "add printer" button in "Step 3 of 3") Is there any place on the disk i should check permissions, or something ? I don't know where to go for debugging this. I'm on irc ('orzel') if needed.
As I said you should not require to be root if the user trying to add the queue is in the lpadmin group. Can you please try if you are able to set up the printer queue using the cups web-interface. Also installing cups used to help in such strange cases. Did you try to enter the credentials of the user which is member of the lpadmin group when being asked for a password?
Any news here? Btw. I meant re-installing cups in my last comment.
I uninstalled hplip/cups and re-installed them, but the behaviour was the same. I kinda have some improvement if i change my /etc/cups/client.conf. It had ServerName 10.11.3.1 because my first (usb-only) printer is 'shared' by the router 10.11.3.1 running linux/cups. If i put ServerName /run/cups/cups.sock and start cupsd, then hp-setup seem to work. But i can't use my first printer anymore.

When you were asked for a password did you try to enter the credentials of the user which is member of the lpadmin group? Also are you able to add the user with the cups web interface?
Additionally your printer requires a binary plugin (hplip-plugin). Do you have it installed properly?
