exifautotran, which is part of media-libs/jpeg, but not from upstream, but a gentoo-own script, doesn't rotate the thumbnail of an image. That could be confusing as after rotation, you see the thumbnail in wrong direction, e.g. in gwenview.
Hanno, starting from >=media-libs/jpeg-7 we are using a Debian copy of exifautotran. -> This bug should be reported to Debian bugtracking system.
