Summary: XMP metadata fails to write to file
Product: digikam
Version: 7.2.0
Platform: Compiled Sources
OS: Microsoft Windows
Status: REPORTED
Severity: normal
Priority: NOR

Test file which reproduces XMP data fail to write
SUMMARY
XMP metadata is failing to write to a file. Based on testing, this appears to
be caused by corrupted existing face data (mwg-rs) already in the file. digiKam
does not provide any error message to let the user know there is an issue.
STEPS TO REPRODUCE
1. Load the attached file in digiKam
2. Read existing metadata (Item > Reread metadata from file)
3. Add new face tag data
4. Write metadata to file (Item > Write metadata to file)
5. Check the metadata of the file
OBSERVED RESULT
New face tag data is not written to the file as expected.
EXPECTED RESULT
File would contain newly added face tag metadata.
SOFTWARE/OS VERSIONS
Windows: 10.0.19042 Build 19042 (Microsoft Windows 10 Pro)
digiKam version: 7.2.0-rc
ADDITIONAL INFORMATION
I believe this is caused by corrupted existing face data already in the file
under the "mwg-rs" XMP tag. I can resolve the error by removing mwg-rs metadata
using the 3rd-party tool exiftool, then rewriting the face tag data in digiKam.
Note: I recently upgraded from digiKam 6.4 to 7.2.0-rc. I am unclear if this
upgrade introduced the corrupted XMP data.
