Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-16-generic x86_64
Distribution: Ubuntu 15.04

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

Ajout d'un raccourci à la barre de raccourci.
Dans le menu kde simplifié, clic droit sur une application (chromium par exemple) puis sélectionner ajouter à la barre de raccourci.
Même en rédémarrant plasma après le plantage, l'application se plante à nouveau. Je dois rebooter le système en espérant que plasma ne plante pas au démarrage.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
