Bug ID: 363196
Summary: kwin crashes at least once as soon as I do anything
with the desktop
Product: kwin
Version: 5.6.4
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: pne...@gmx.com
Application: kwin_x11 (5.6.4)
Qt Version: 5.6.0
Frameworks Version: 5.22.0
Operating System: Linux 4.5.4-1-ck x86_64
Distribution: "Arch Linux"
-- Information about the crash:
- What I was doing when the application crashed:
I was bringing up the browser, or clicking on an icon, it really doesn;t matter
what I do, just moving the cursor on the desk top will cause kwin to crash.
I downloaded all the qt debugging files and just recompiled kwin and loaded it
through pacman, reboot and here is the error.
- Unusual behavior I noticed: Almost aways the same error or in same place if
that is the right term to use. Usually I just restart the application and it
will run fine for the session or it may crash again and in htop i'll notice
entries that read /usr/bin/kwin_x11 ---crashes 1
--Other Notes:
I've only just recomplied kwin, please let me know if I need to recomplied and
other modules.
THanks
The crash can be reproduced every time.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
