Description syl-shirts 2016-01-11 00:02:21 UTC 
Application: systemsettings5 (5.4.1)

Qt Version: 5.5.0
Operating System: Linux 4.1.12-1-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

I installed an HP Photosmart 6515 printer as the first printer for a fresh openSUSE Leap 42.1 64-bit installation under VirtualBox 5.0.12.

The settings were: AppSocket/HP JetDirect, port 9100, manually entered IP address
Driver: HP Photosmart 6510 Series, hpcups 3.14.6 driver

While still in the Printer Settings app, I chose to uninstall this printer.

This caused "Configure Desktop"/System Settings to crash.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Addition info:
I had set Name to "Photosmart6515", Description to "Photosmart 6515" and left Location blank.

I also unchecked "Share this printer"

Between creating and trying to remove the printer I had clicked on the "Configure" button w/o changing any settings and then clicked the "Maintenance" button w/o selecting "Print Test Page" (I clicked elsewhere in the window to dismiss selection).

At this point I clicked "Remove Printer"
