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

rien, ça s'est planté tout seul
je ne peux rien dire de plus puisque depuis que maga est distribué ça se plante tous les jours, vivement le retour de mageia 5, mageia 6 ne marche pas, c'est inadmissible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Bus error
