Hi,
The trace in comment #1 is not a bug really. it's a guard from exiv2 to prevent
to corrupt a jpeg file when you backport metadata from non standard jpeg
standard.
Typically, a jpeg segment cannot store more than 64Kb. A JPEG segment is used
to store the whole Exif byte array to the image.
Exif.PentaxDng.0x0406 tags is not a standard Exif tag. It's a makernote which
is a bulk of data not documented stored by Pentax for DNG processing.
Adobe as extended the standard Exif to be able to use more than one JPEG
segment concatened, but i'm not sure that Exiv2 support this mode.
So, when DK process this kind of JPEG Pentax file, a new JPEG temporary file is
created at save process, it ask to Exiv2 in backport original JPEG Exif to new
file and call "Houston control room"
The solution is to append Exif.PentaxDng.0x0406 to the backlist tags list that
DK include before to process with Exiv2.
