-- Information about the crash:
====Basic information====
I went to create a custom shortcut, changed my mind, backed out discarding
changes which caused a crash.

====Duplication steps====
1. Open System Settings, navigate to Shortcuts > Custom Shortcuts.
2. Click Edit > New > Global Shortcut > Shortcut/URL
3. In the Trigger tab, specify a keyboard shortcut.
4. Close the Settings window, clicking **Discard** in the popup.

The reporter is unsure if this crash is reproducible.

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