Just noticed these while looking at phil's dng 1.3 change:
Validating "CRW_3669.DNG"...
*** Warning: IFD 0 DateTime is not a valid date/time ***
*** Warning: IFD 0 DateTime has non-ASCII characters ***
*** Warning: GPS IFD GPSLatitudeRef is not NULL terminated ***
*** Warning: GPS IFD GPSLatitudeRef has non-ASCII characters ***
*** Warning: GPS IFD GPSLongitudeRef is not NULL terminated ***
*** Warning: GPS IFD GPSLongitudeRef has non-ASCII characters ***
*** Warning: GPS IFD GPSStatus is not NULL terminated ***
*** Warning: GPS IFD GPSStatus has non-ASCII characters ***
These date and gps values show garbage characters in picasa properties, so this isn't purely cosmetic. Note this is on a camera without GPS, using the latest trunk.
dng_validate is included in the DNG SDK
