Application: plasma-desktop (4.11.14)
KDE Platform Version: 4.14.3
Qt Version: 4.8.6
Operating System: Linux 3.16.7-7-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
I restarted a destkop application which uses a special kind of window configuration (it has some windows which are aligned on top as menu and on bottom as status line and they are always in background. Other windows can't overlap them and also the maximize function would not overlap that area).

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma-Desktop-Umgebung (plasma-desktop), signal: Segmentation fault
