With the last Beta 9SP3B2, when using a Batch Process just to re-size the pictures in order to share with others I get this message for every file:
<5774> IMG_20150601_165248.jpg: Unable to update XMP, error #000000c9: XML parsing failure
<6040> M:\2015\2015-06 (Jun)\small1\IMG_20150601_165248.jpg: XMP Metdata cannot be stored in file type 'jpg'
It was working right in the previous versions and Betas. As consequence of the error, it doesn't copy all the original EXIF and Metadata from the origin pictures to the destination. Really a bad thing because I had to go back to the previous Beta.
