-- Information about the crash:
After looking through the available options in the Settings Dialogue I exited and the Application Crashed. The only thing that was untoward was when I was try to change the themes *background colours, i.e. Air for Laptops) when changed and apply was pressed a message popped up saying "malformed URL" (could have been "misformed")

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