Thanks for all the info, it is as I expected, your cupsd.conf has "Browsing No" because you do not use printer sharing. Then the DNS-SD host name is not set in the daemon's internal variable DNSSDHostName and this variable I compared with the host name of the URI of the potential new queue to see whether I have to change it to "localhost" for the case that the printer is a local service (IPP-over-USB, Printer Application, ...). This caused the crash. Now I have added a fallback to the internal variable ServerName if DNSSDHostName is NULL.
I could reproduce the bug by doing the command cupsctl --no-share-printers (I had printer sharing on for my OpenPrinting work) and re-trying to access an IPP printer through GTK's print dialog which caused the crash then for me. I have the fix now ready and with it the crash goes away. I will update the Pull Request on CUPS upstream (https://github.com/OpenPrinting/cups/pull/353) and also the patch on the Ubuntu package.
