Bug ID: 360843
Summary: Plasma crash when manually reordering windows in
window bar
Product: kde
Version: unspecified
Platform: unspecified
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: eiapopei...@online.de
Application: plasma-desktop (4.11.14)
KDE Platform Version: 4.14.13
Qt Version: 4.8.6
Operating System: Linux 3.13.0-83-generic x86_64
Distribution: Ubuntu 14.04.4 LTS
-- Information about the crash:
- What I was doing when the application crashed:
I was manually reordering windows in window bar. By accident I pulled the
window too much down and this started a change of virtual desktop. When I
switched back to the original one and dropped the window in the windows bar,
plasma crashed.
- Custom settings of the application:
* allow manuallordering in the windows bar
* allow virtual desktop switch when rolling over screen edges with the mouse
Sorry for my englisch. I do not know the englisch names because I use a german
distro.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma-Desktop-Umgebung (plasma-desktop), signal: Segmentation
