Bug ID: 374002
Summary: kwin_x11 crash every time I login
Product: kwin
Version: 5.8.3
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: spalmr...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.8.3)
(Compiled from sources)
Qt Version: 5.6.2
Frameworks Version: 5.26.0
Operating System: Linux 4.8.15-gentoo x86_64
Distribution (Platform): Gentoo Packages
-- Information about the crash:
- What I was doing when the application crashed:
Logging in to KDE crashes kwin_x11 every time. I think this is related to bug
#361236 but DrKonqi doesn't seem to allow me to add to that report. I just
wanted to upload my backtrace in case it's helpful.
The crash can be reproduced every time.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
