Bug ID: 357511
Summary: Kwin crashes and automatically restarts
Product: kwin
Version: 5.4.3
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: sisie...@email.cz
Application: kwin_x11 (5.4.3)
Qt Version: 5.5.1
Operating System: Linux 4.1.13-5-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"
-- Information about the crash:
PC: board Q1900M, 8GB RAM, 1 TB HDD. OS: OpenSuSE Leap 42.1, KDE Plasma 5,
opened applications: Claws Mail, Okular. When trying to open Slimjet Kwin
suddenly crashes and restarts again (this case) or sometimes X system totally
freezes. This behavior is deterministic. If using other applications too the
crash comes irregularly.
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".
