Bug ID: 500400
Summary: org.kde.plasma.taskmanager/contents/ui/Task.qml:79:
TypeError: Cannot read property 'status' of null
Classification: Plasma
Product: plasmashell
Version: git-stable-Plasma/6.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: Task Manager and Icons-Only Task Manager widgets
Assignee: plasma-b...@kde.org
Reporter: citrus-jump...@icloud.com

Target Milestone: 1.0

The session journalctl log.
SUMMARY
Under specific (but not entirely known) circumstances (presumably using the
system with multiple virtual desktops and post-wake from sleep), launching some
applications can entirely freeze plasmashell, causing the appearance of a
frozen screen. The system still operates behind the frozen graphics. This has
been observed with the Telegram Desktop Flatpak and GPU Screen Recorder
specficially, though it's not likely that thee applications are specific
culprits.
Immediately force shutting down the system and viewing the previous boot logs
on the next boot by using `sudo journalctl --no-hostname -b -1`, the logs
continue as normal until a type error is reached. This, presumably, causes the
freeze.

STEPS TO REPRODUCE
1. Have a set up with 4x4 virtual desktops, and a panel with Icons Only Task
Manager.
2. Sleep the system, mess around with applications on multiple virtual
desktops.
3. Launch (presumably) any application.
OBSERVED RESULT
The system's graphics (and presumably input) are frozen. The system still
operates behind the scenes. Media still plays, network connections are still
active etc.
EXPECTED RESULT
The Icons-Only Task Manager widget operates as normal, and does not crash
plasmashell when launching some applications under specific (though not
entirely known) circumstances.
