Bug ID: 381895
Summary: KWin crashed and immediately restarted while adding
virtual desktops via Desktop Grid
Product: kwin
Version: 5.10.3
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: ja...@nerdonthestreet.com
Target Milestone: ---
Application: kwin_x11 (5.10.3)
Qt Version: 5.9.0
Frameworks Version: 5.35.0
Operating System: Linux 4.11.7-1-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- What I was doing when the application crashed:
Clicking the "+" button in the Desktop Grid to add more virtual desktops.
This bug report was submitted through the Crash Reporting Assistant. I have
compiled KWin with debugging enabled because it has been less stable recently
on my Arch system. I am willing to compile additional packages with debugging
enabled if it will lead to more useful information for the developers. I am
using the proprietary NVIDIA driver.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
