I can see that Baloo is trying to remove the entry for a deleted file, but the trace does not show what file.

It *might* be possible to see more with debugging, you can turn on debugging by creating a qtlogging.ini file:

    mkdir -p ~/.config/QtProject
    vi ~/.config/QtProject/qtlogging.ini

and adding

    [rules]
    kf.baloo=true
    kf.baloo.engine=true

You can also ensure that any log or error messages sent to stderr get copied to the journal by editing the kde-baloo unit file:

    systemctl edit --user kde-baloo

and add line:

    [Service]
    StandardError=journal

and saving the override.
