Bug 386147

After checking out the new vault feature, I decided I didn't want the icon showing all the time in the systray and used the settings to hide it. After closing the systray settings, the icon was still showing for a second and then plasmashell crashed.

The backtrace seems to implicate kf5windowsystem and QML though:
