I think it is the same bug. The first command embeds the icc profile,
hence eog works as expected.

The second command does not embed any profile (even that asked to do so)
so the output srgb.jpg is "stripped", too.
BTW, when you run "$ jpegicc -e -v -o sRGB.icm stripped.jpg srgb2.jpg",
the profile is embedded.
