No, the image was imported directly from the camera to Shotwell on a Jessie system. I'm afraid I don't remember how I got the image out of Shotwell. Hmm. If I look at the directory in Shotwell's storage area using any of Thunar, Nautilus, or Caja, the file appears unrotated (landscape orientation). It has an md5sum of 306c0a274435016922cea2f3c1898819 and jpegexiforient says it has an Exif Orientation Tag of 1. Maybe I rotated the file outside Shotwell (e.g., using Eye of GNOME or Eye of MATE). But I think that trying to figure out how I produced the image is a distraction. I have a copy of the sample file (message #10 of the bug report) in a separate folder, on both the Jessie system and the Stretch VM that I submitted the bug from. The md5sum for this file is 5445cbb90960a93259db3b7045cdaf77 and jpegexiforient says it has an orientation of 8. On Jessie: If I open that folder using Caja or Nautilus, the sample file appears rotated. If I open the same folder using Thunar, it appears unrotated. (I can have both Caja and Thunar open at the same time; Caja shows the image rotated, Thunar shows it unrotated.) If I open the sample file using GIMP, I get a popup saying that the exif data says the image should be rotated and do I want to do that. If I click on Rotate, I get the rotated image. If I dismiss the popup, I get the unrotated image. So perhaps with Thunar the exif data is getting ignored when the thumbnail is generated. On Stretch: It depends on which program I run first. If I delete the cached thumbnails and then view the folder using Caja, both Caja and Thunar show the image as rotated. If I clear the thumbnail cache again and then view the folder using Thunar, both Caja and Thunar show the image as unrotated. (I guess with Stretch they share the same thumbnail cache?) I hope this gives you the information you were looking for. If not, let me know what I missed and I'll try again. cheers, mike
