Application: plasmashell (5.5.1)

Qt Version: 5.5.1
Operating System: Linux 4.3.2-desktop-2.mga6 x86_64
Distribution: "Mageia 6"

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

Before login to the session I removed cache and config directories (~/.cache, ~/.config, ~/.local).
After login I moved bottom panel to the right edge and resize it a bit. Later I downloaded and applied plasma style/look: "Classic Glass". After that I would like to add some plasmoids to desktop and plasmashell crashed.

Plasma 5.5.1, KFrameworks 5.17.0, Qt-5.5.1

-- Backtrace:
Application: Plazma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
