SUMMARY KRunner fails to list or search for Plasma Activities on Arch Linux. Despite the plasma-kactivitymanagerd.service being active and activities being correctly reported via D-Bus, KRunner returns no results. The service logs a persistent SQL syntax error that prevents metadata from being indexed or served to KRunner.

STEPS TO REPRODUCE

    Create one or more Activities in System Settings.

    Open KRunner (Alt+Space).

    Type the name of an existing Activity (e.g., "Lavoro").

    Observe that no Activity results are shown.

    Check the log file at ~/.local/share/kactivitymanagerd/resources/errors.log.

OBSERVED RESULT KRunner returns no results for activities. The log file consistently shows: error: near ".": syntax error Impossibile eseguire il comando Attempts to mitigate this by setting kactivitymanagerd_plugin_sqliteEnabled=false in kactivitymanagerdrc do not stop the error from appearing, nor do they restore KRunner functionality.

EXPECTED RESULT KRunner should correctly display matching Activities and allow switching between them.

SOFTWARE/OS VERSIONS

    Operating System: Arch Linux

    KDE Plasma Version: 6.5.4

    KDE Frameworks Version: 6.21.0

    Qt Version: 6.10.1

    Kernel Version: 6.18.2-arch2-1 (64-bit)

    Graphics Platform: Wayland

ADDITIONAL INFORMATION

    Manual D-Bus calls (qdbus6 org.kde.ActivityManager /ActivityManager/Activities ListActivities) correctly return the Activity IDs, but ActivityName often returns empty even when defined in kactivitymanagerdrc.

    The syntax error near "." appears immediately upon service restart, even after deleting the ~/.local/share/kactivitymanagerd/resources/ directory.

    This suggests an invalid SQL query (possibly a malformed PRAGMA or table reference) generated by the daemon that is incompatible with current SQLite versions.

    Reinstalling kactivitymanagerd and kactivities-stats does not fix the issue.
