 While I can reproduce the problem, for me the displayed messages are these:
TIFFReadDirectory: Warning, Photometric tag is missing, assuming data is YCbCr.
TIFFReadDirectory: Warning, SamplesPerPixel tag is missing, applying
correct SamplesPerPixel value of 3.
OJPEGSubsamplingCorrect: Warning, Subsampling tag is not set, yet
subsampling inside JPEG data [2,1] does not match default values
[2,2]; assuming subsampling inside JPEG data is correct.
OJPEGSetupDecode: Warning, Depreciated and troublesome old-style JPEG
compression mode, please convert to new-style JPEG compression and
notify vendor of writing software.
OJPEGWriteHeaderInfo: jpeg_start_decompress() returned image_width =
4272 and image_height = 2848, expected 4272 and -1.

 For me this seems to be tiff checks that became stricter to prevent
accidental crashes due to images not conforming the standards.
As such the warnings show the sign of badly written OJPEG format that
don't conform the standard.

 Got it, as you could see above.
