Bug ID: 428975
Summary: kwin crashes when opening applications
Product: kwin
Version: 5.17.5
Platform: Debian stable
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: chaim....@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.17.5)
Qt Version: 5.15.1
Frameworks Version: 5.74.0
Operating System: Linux 5.9.0-1-amd64 x86_64
Distribution: Debian GNU/Linux bullseye/sid
-- Information about the crash:
- What I was doing when the application crashed:
The problem is always directly visible when starting KDE after logging in.
- Unusual behavior I noticed:
Kwin tries to start the application several times before giving up.
Starting "kwin --replace" reproduces the result and gives the following output
(only first part shown):
Application::crashHandler() called with signal 11; recent crashes: 3
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = kwin_x11 path = /usr/bin pid = 23486
KCrash: Arguments: /usr/bin/kwin_x11 --crashes 2
KCrash: Attempting to start /usr/lib/x86_64-linux-gnu/libexec/drkonqi
