Bug ID: 352079
Summary: System Settings crash (Appearance / Application Style/
Window Decorations)
Product: kde
Version: unspecified
Platform: unspecified
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: unassigned-bugs@kde.org
Reporter: moilinki@gmail.com
Application: systemsettings5 (5.2.2)
Qt Version: 5.4.1
Operating System: Linux 3.19.0-26-generic x86_64
Distribution: Ubuntu 15.04
-- Information about the crash:
- What I was doing when the application crashed:
Run "System Settings" from the KDE Application Launcher ("Launcher to start
applications"). Choose "Appearance" / "Application Style" and finally click
"Window Decorations". Badaboom. I tried three times, and always crashes.
- Unusual behavior I noticed:
Earlier, after several "graphics resets" , I had what seemed like old style
window manager crash - Windows were without decorations and all over the place
(virtual desktops collapsed to a single desktop) without possiblity to control
them. To get control back, I switched to virtual console, and run
"(DISPLAY=:0.0 kwin_x11) &" from the terminal. I do not know if this is the
correct thing to run in the newest KDE, but it did bring window frames, title
bars and other decorations back and I could once again control the application
windows. The only annoying problem was that the windows title bar text was
unconfortably huge, which felt me feel like I am treated like a semi blind 100
years old grandpa. So off I went to fix the situation using System Settings,
hence the crash and this report.
I am running Kubuntu 15.04 (which presents to me various kind of KDE related
stability issues).
The crash can be reproduced every time.
-- Backtrace:
