Bug 449576

SUMMARY
Plasmashell's clock freezes frequently so i kill plasmashell and start it again via either KRunner. This time however KRunner didn't show up on Alt + F2 so i opened the terminal Ctrl + Atl + T and run `plasmashell &`.
Plasmashell started and immediately crashed, and it started a constant loop of starting & crashing. I have something like 20 plasmashell crashes listed before i managed to logout via the terminal. Focus was lost constantly and typing into text fields was constantly interrupted. On top of this each time plasmashell started KRunner would appear and catch/capture the text that was being typed into some other app. Like it was trying to compensate for not starting during the time when plasmashell was killed by me. However i have not pressed Alt + F2 so many times as KRunner has appeared...


STEPS TO REPRODUCE
1. Send plasmashell a SIGTERM or SIGKILL
2. Open terminal
3. Run `plasmashell &`
