So, eof shipped with FC4 should be capable of preserving EXIF data. I 
have found out that it really does preserve EXIF data, but 
unfortunately not for all picture files.

The behavior of eog regarding EXIF preserving depends on yet unknown 
condition - for some pictures it preserves EXIF data, for some does 
not.

The only thing I have realized so far is that the EXIF-preservation 
behavior depends on location of the file: If I copy the same picture 
(e.g. "/home/media/Pictures/prvnich\ 430\ fotek/pict0400.jpg")  to 
~/Desktop and apply rotation on it and than save it, EXIF data will be 
preserved. However, if I rotate+save it in 
"/home/media/Pictures/prvnich\ 430\ fotek/", EXIF tags will not be 
preserved.

The directory's permissions are set to 775 and owners are 
root:my_group. The pictures in this directory are owned by 
my_user:my_user. my_user is member of my_group.
