Created attachment 8215 Comparison between thumbnail and real image orientation. Hi! First at all, I think this is a tumbler bug, but could be a Thunar bug. I don't know. ;) The bug is: thumbnails do not are genearted with the correct orientation. See the attatchment where the picture is "landcape oriented" but the Thunar thumbnail is "portrait oriented". Thanks!
It reminds me of Bug 14644, maybe the picture uses the orientation metadata. Can you attach the file the is incorrectly thumbnailed?

First image: The actual image. Second one: How Thunar shows the thumbnails of the image (the 3rd and 4th appear rotated).
Created attachment 8707 screenshot Looks good here. Are you using the latest version of tumbler and thunar? Also try to clear the thumbnail cache (~/.cache/thumbnails).

Created attachment 8715 Original file
Created attachment 8718 tumbler.diff It's possible to reproduce the issue with the last attached image. I know almost nothig of exif, possibly this image contains invalid metadata or tumbler's code is naive, because it uses a union to store either tiff or jpeg metadata, but when reading this image both are set (at tvtj_exif_parse_ifd). When thumb_jpeg.orientation is checked, its value is garbled because the union is now supposed to store thumb_tiff. I was able to fix the problem with the attached diff, however there could be drawbacks besides increased memory usage (very very small AFAICT).

Thank you so much! ;)
I'm sorry but I still see this issue on openSUSE Tumbleweed with Xfce 4.14 / Thunar 1.8.11, should I open a new bug?
Oops, I just noticed this is a Tumbler bug and there was no release with the fix yet, my bad
