Created attachment 142779 [details]
Example TIFF file

Try to insert the attached file to any LibO application.
It is taken from http://maptools-org.996276.n3.nabble.com/JPEG-compressed-RGB-tiled-TIFF-with-chroma-subsampling-tp14062p14076.html

Original investigation concerned this file: http://forumooo.ru/index.php?action=dlattach;topic=7201.0;attach=12329

Confirmed by kompi already with the forumooo.ru file.

Thanks to boud of Krita for help. Boud commented:
"krita does support YCbCrA, but other applications will automatically convert it to rgb. But because there are no free ycbcra profiles, we don't ship them. If the user downloads one from somewhere, this image can be loaded without conversion"
