Distribution (Platform): Exherbo Packages

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

Everytime I keep the mouse on a task in the task manager, plasmashell crash at the moment of displaying the miniature.

- Unusual behavior I noticed:

Only the borders of the window' miniature are dispalyed, the central part is transparent and nor the name of the window, nor the preview are displayed. The miniature is transparent. The crash occures ~ 1 or 2 seconds after the displaying of minature' borders.

The crash occures eveytime the mouse hover a task and the miniature is displayed, with all kinds of apps (chromium, konsole, settings, ...).

The crash can be reproduced every time.

-- Backtrace:
