It seems that Kipi uses the convert tool from ImageMagick.
I Installed the exif tool and tried to compress pictures by hand to see what happens with my exif data.
Extracting the exif information from the original picture goes fine.
After recompressing it the exif tool complains that the data is corrupt.
stephane@nausicaa:~$ exif IMG_0080.JPG > IMG_0080.exif
stephane@nausicaa:~$ convert -quality 80 IMG_0080.JPG IMG_0080_2.JPG
stephane@nausicaa:~$ exif IMG_0080_2.JPG > IMG_0080_2.exif
