Maybe this should go into a new thread (and maybe it doesn't matter at all).
I've stumbled across some more information. It appears the messages are
triggered by TIFF files that came from NEFs. Here is what I see:
All of the TIFF files in my database are of the pattern %Arboretum.tif (I
only have 4 or 5, all from the same film roll). I created the TIFF files in
darktable from raw NEF files (I was going to feed the TIFF files into a
panorama program). If I filter images by filename and select %Arboretum.tif
and close darktable, the next time I open darktable I get those unknown
field warnings on the command line (I'm launching darktable from the
command line).
If I filter to %Arboretum.NEF, I do not get the warnings when I open
darktable. And if I just filter to %Arboretum%, I do not see the TIFF files
immediately; they are grouped with their "original" NEF files. When I
ungroup them, it triggers the field tag warning.
So, it appears that TIFF files generated by darktable contain the unknown
field issue. Is that because they came from NEFs with crazy manufacturer
fields? And darktable (or a library it is using) is suppressing those
messages when processing RAWs but not when processing TIFFs?
