Yes, I suspect that tag handling is not as robust as it might be. <br>
What does your "script that will rebuild the Tree" actually do?<br>
<br>
Going on from that can anyone tell me which Tag modification actions<br>
write to the database and which write to the image metadata? ... and<br>
why doesn't Digikam always write to both?<br>
