I tried exiftran, and it gives the same (bad) result as jpegtran. I suppose they use the same code.

The bug is also present in KDE4; Gwenview 2.1 / KDE 4.0.98. (Note that Gwenview caches the image to be displayed, so right after the rotation it will look all right. You have to exit Gwenview and start it again to see the problem.)

Also: It does not seem to be the case that the input files are malformed; I get the same result when I create a 2592x1944 pixel image in the GIMP (v. 2.4.5) and save it with the standard jpeg options.

Any proposed workaround for this? Is there any program out there that does the rotation properly? Non-lossless rotation would always work of course, but that is not ideal. (Note that if you happen to own a camera that produces pictures in the "wrong" format, this bug will apply to *all* your photos.)
