Description ngcreeper 2020-04-06 16:57:10 UTC 
Application: systemsettings5 (5.18.4)

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to add new emoticons via the system settings, but then it crashed when I clicked on "Get New Emoticons". It only happened once; it never happened again when I  tried to do the same thing.

The crash does not seem to be reproducible.

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