Description Ervan Darnell 2023-10-26 19:12:17 UTC 
SUMMARY
***
While processing faces and adding names directly under the face thumbnail under the "People" menu option and the tag "People/Don Baker" in the "Unconfirmed" section, the following crash happened.  It has happened multiple times, but cannot be directly repeated because the face in question gets processed before the crash.  I am hoping the fact that this happens on .PDFs is a sufficient clue.
***


OBSERVED RESULT
Crash with:
Cannot load metadata with Exiv2:  (Error # 12 :  "/home/ervan/Pictures/WinPictures/Personal/_gsdata_/_saved_/2011/Don's wedding/his pics/Documents/Invitations/SaveTheDate.pdf: The file contains data of an unknown image type"

ADDITIONAL INFORMATION
Comment 1 Maik Qualmann 2023-10-26 19:37:29 UTC 
A quick test here shows no crash with an image in a PDF file. However, it is clear that metadata can only be written to PDF files using the ExifTool writing engine. I suspect a crash in the Image Magick Loader for PDF files or in the Exiv2 library. Have you activated ExifTool for writing metadata? If not, please test whether the crash still occurs with ExifTool as metadata writer.

To better isolate the error, download the AppImage with "debug" in the filename and run it with "debug" as an option. If the crash occurred write "bt" + Enter and then post the output in the terminal here.

Comment 3 Ervan Darnell 2023-10-27 19:51:22 UTC 
"Sync Metadata and Database" is not even checked for the moment.  This seems to be where I use exiftool for writing the metadata?  Apparently it is reading the metadata some other way.  But, still you want me to turn this on for testing.  Right?

Comment 6 Michael Miller 2025-02-02 12:48:48 UTC 
Closing due to no response from user, and the entire face pipeline has been rewritten since this issue was created.

Cheers,
Mike

I cannot replicate the failure in 8.5.0 (original filer here).  Thanks.
