I am getting two different errors when trying to write IPTC/XMP data to the file at: www.o-day.net/test/images/4176355

If I give the file a .jpg extension, the exiftool reports a "Format error in file" error. If I remove the extension I get a "Error parsing XMP" error.

I get no error when I try to read the IPTC data from the file. No XMP data comes out at all.

I know we worked through something similar to this before and there was an update made that allowed these types of files to be written to.

Any thoughts?
