Sentry Crash Report:

Description Al 2019-08-06 04:42:28 UTC 
SUMMARY
When new raw images, in my case fujifilm *.raf files with *.raf.xmp files , are added to the system the tags listed in the associated sidecar file are not showing up in the album view. When *.jpg from the same camera are added there is no problem.
The sidecar files were previously generated by digikam, I just rebuilt the database and was expecting that all the tags I had added were going to be there because the .xmp files were present.
The tags are visible in the metadata view.
What I add a tag back in manually the existing tags, as seen in the metadata view, are lost


STEPS TO REPRODUCE
1. copy a *.raf image file and sidecar file to a folder that is being managed by digikam.

OBSERVED RESULT
2. look for xmp metadata, it shows some tags.
3. Look at album view, not tags show up
4. Add a new tag, the existing tags seen in the metadata view are replaced.


EXPECTED RESULT
The tags that are in the .xmp file will show up in the album view.

The reading of sidecar files is activated? Please send me a RAW + sidecar on my private e-mail.

Comment 2 Maik Qualmann 2019-08-06 11:25:55 UTC 
Are the RAW files with the sidecars in an existing collection? Or did you add the RAW files over the copy / paste function?

I actually see a problem with the normal copying process here. There is a possibility that the RAW will be copied in front of the sidecar and digiKam will not "see" the sidecar file. A re-reading of the metadata would help.

I'll change the function to always copy all the sidecars first and then the image files.
