Bug ID: 385849
Summary: kwin_x11 crashed during entry to chromium address bar
Product: kwin
Version: 5.11.0
Platform: Gentoo Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Application: kwin_x11 (5.11.0)
Qt Version: 5.9.2
Frameworks Version: 5.39.0
Operating System: Linux 4.13.7 x86_64
Distribution: "Gentoo Base System release 2.4.1"
-- Information about the crash:
For me, it is totally unclear if this was just concidentally or really causally
related… but
- What I was doing when the application crashed: Adding a site search in the
chromium tab bar of a maximised chromium window.
Funny enough, I couldn't find this exact chromium window after kwin_x11 has
restarted. I could not reproduce this issue with the same action. Honestly,
sometimes kwin_x11 just restarts and I do not think that it is correlated to
specific actions.
Distribution is Gentoo with frameworks 5.39, plasma 5.11, and apps 17.08.2.
Thanks for the nice working environment and good luck making it even better!
The crash does not seem to be reproducible.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
