Description Eric 2017-03-07 06:22:25 UTC 
Application: kwin_x11 (5.8.3)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.49-16-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:
On starting a VirtualBox client (Windows 10) with two screens, one window will sometimes fail during startup. Disabling and restarting the second screen resolves the symptom.

VirtualBox Graphical User Interface
Version 5.1.14 r112924 (Qt5.6.1)
NAME="openSUSE Leap"
VERSION="42.2"
ID=opensuse
ID_LIKE="suse"
VERSION_ID="42.2"
PRETTY_NAME="openSUSE Leap 42.2"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:opensuse:leap:42.2"
BUG_REPORT_URL="https://bugs.opensuse.org"
HOME_URL="https://www.opensuse.org/

The problem is a reasonably new one, 4-6 weeks and I believe due to a OpenSUSE patch. VBOX has remained at the above version since it was released.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault

Unfortunately the backtrace is lacking debug symbols. If you are able to 
reproduce please install the debug packages provided by your 
distribution (please ask the distribution support channel on how to 
install them) and attach a new backtrace.
