Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-34-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:

Clicked the Application Launcher button, used the Search function, typed „Intel”, clicked the Intel Graphics Update Tool application and then Plasmashell crashed. After relaunch of the app, Plasmashell has not crashed.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
