Description Mike Morrison 2020-12-08 01:23:47 UTC 
SUMMARY
When digiKam automatically renames an image to resolve a duplicate filename during a move, the existing image's face tags can be lost. Additionally, the caption from the moved image can be incorrectly moved to the existing image.

STEPS TO REPRODUCE
1. Start with 2 different images, having the same filename, in 2 different albums. For example:
In album "Friends", have a photo of a person, called "photo.jpg".
In album "Plants", have a photo of a flower, called "photo.jpg".

2. Apply a face tag (e.g. "Mike") to a region of the person photo.

3. Apply a caption (e.g. "A nice flower") to the flower photo.

4. Right-click the flower photo and choose "Move to Album..."

5. Choose the "Friends" album as the destination.

6. digiKam will warn of a file conflict. Choose "Rename automatically".

7. Look in the "Friends" album. Both photos are there. The flower photo has been renamed to "photo_v1.jpg". But:

OBSERVED RESULT
The person's photo has lost its face tag.
The caption "A nice flower" has been removed from the flower photo, and applied to the person's photo.

EXPECTED RESULT
The person's photo should keep its face tag.
The flower photo should keep its caption.
The flower caption should not be applied to the person's photo.

Comment 1 Maik Qualmann 2020-12-08 07:37:51 UTC 
This is a problem with the Scan Controller. The hints that we give him on the way to the later scan are no longer correct because the file name has changed.
