Bug ID: 445375
Summary: KWin restarts after Virt-Manager adds new component to
a VM
Product: kwin
Version: 5.23.2
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: slavom...@hotmail.com
Target Milestone: ---
Application: kwin_x11 (5.23.2)
Qt Version: 5.15.2
Frameworks Version: 5.87.0
Operating System: Linux 5.14.14-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.23.2 [KCrashBackend]
-- Information about the crash:
- What I was doing when the application crashed:
Added a virtualized hardware component to a VM from within Virt-Manager GUI.
Any component that requeires the VM to restart after being added to the VM
template makes KWin crash and restart. Even if the VM is powered off. Example:
RNG device /dev/urandom
Aadding components that do not require the VM to be restarted will not make
KWin crash. Example: virtual network interface
The crash can be reproduced every time.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = {<No data
fields>}}
