Package: plasma-discover
Version: 5.26.4-1+b1
Severity: normal
X-Debbugs-Cc: onit...@gmail.com
Dear Maintainer,
On systems running the KDE Plasma desktop together with plasma-discover, some
system tray icons regularly vanish. This mostly happens right after desktop
startup, but can also occur at any later point.
Uninstalling plasma-discover and its dependencies causes the problem to
disappear completely.
After analyzing the systemd user session (systemctl --user --failed) and the
crashed plasma-kded service, I looked at the coredump (coredumpctl gdb).
The service's journal (journalctl --user -xu plasma-kded.service) did not
provide any insights.
An example backtrace of kded5 is attached below. The trace suggests that the
actual problem may be with libpackagekitqt5, but I cannot say for sure.
