            Bug ID: 495107
           Summary: Plasma reports multiple crashes after logging in
    Classification: Frameworks and Libraries
           Product: frameworks-kded
           Version: 6.7.0
          Platform: openSUSE
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kio-bugs-n...@kde.org
          Reporter: arcangelze...@gmail.com
                CC: kdelibs-b...@kde.org
  Target Milestone: ---

Application: kded6 (6.7.0)

ApplicationNotResponding [ANR]: false
Qt Version: 6.8.0
Frameworks Version: 6.7.0
Operating System: Linux 6.11.3-1-default x86_64
Windowing System: Wayland
Distribution: "openSUSE Tumbleweed"
DrKonqi: 6.2.1 [CoredumpBackend]

-- Information about the crash:
After updating the system approximately 10/18/2024, logging into the system
shows several crash reports from KDE (Power management, Kactivitymanagerd,
KDEConnect,and others) that all seem to have the exact same crash reports. 

Uncertain if it's related but a KDEWallet prompt is now coming up where it
hasn't before as well.

It appears to be related to
QtWaylandClient::QWaylandTabletPadV2::zwp_tablet_pad_v2_removed(), but I'm
completely unsure from there.

I do have an XP-Pen Deco Pro MW drawing tablet installed.

The crash can be reproduced every time.

-- Backtrace:
Application: kded6 (kded6), signal: Segmentation fault
