Bug ID: 381496
Summary: "Replacing" kwin crashes it
Product: kwin
Version: 5.10.2
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Application: kwin_x11 (5.10.2)
Qt Version: 5.9.0
Frameworks Version: 5.35.0
Operating System: Linux 4.11.5-1-ARCH x86_64
Distribution: "Arch Linux"
-- Information about the crash:
- What I was doing when the application crashed:
I ran "kwin_x11 --replace" from the KRunner (Alt+F2) - actually saved that into
a script but I don't think that matters.
This bug doesn't break anything except that a popup with "kwin crashed"
appears. After the "restart" process is complete, everything works as expected.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".
