Application: systemsettings5 (5.4.1)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-17-generic x86_64
Distribution: Ubuntu 15.10

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

1. Opened System Settings
2. Selected "Online Accounts"
3. Clicked "+ Create"
4. Selected "Google"
5. Entered my credentials; account was added sucessfully
6. Returned to "Online Accounts" and clicked the "Configure..." button next to Google Hangouts, which was checked
7. System Settings then crashed
8. Subsequent attempts to click the "Configure..." button consistently cause systemsettings to crash and Apport reports "Sorry, Ubuntu 15.10 has experience an internal error."

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
