KimDaBa does not modify the EXIF when I rotate a picture from it.
Instead, it put an attribute 
   <image ... angle="90"  ...>
   </image>
in the index.xml file. Another software has no chance to know about
that information.

void Viewer::rotate90()
{
    currentInfo()->rotate( 90 );
    load();
}

http://webcvs.kde.org/kdeextragear-2/kimdaba/imageinfo.cpp?view=markup
void ImageInfo::rotate( int degrees )
{
    _angle += degrees + 360;
    _angle = _angle % 360;
}
