Thanks Gilles,

I have not had a chance to try out 7.3.0 with Exiftool support, eager to do
so. Back in January, I opened Bug 432265
<https://bugs.kde.org/show_bug.cgi?id=432265>. Attached to the bug there is
a sample file with a problematic XMP condition caused by modifying the Geo
Tags in Windows Photo Gallery.

I am curious to know - In which operations Exiftool is used by Digikam?
