possible bug histogram image staring after IM 6.9.0.0 Q16 Mac OSX

This works fine for IM 6.9.0.0 Q16 Mac OSX Snow Leopard

Code: Select all

im6900 convert rose: -define histogram:unique-colors=false histogram:rose_hist.gif
But for any release after that (ignoring 6901, which is known to be bad), the resulting histogram image is only viewable by IM. All other tools seem to say it is corrupt and cannot open it or show nothing. This includes Mac Preview and Safari, Firefox and Chrome browsers.

Perhaps this is a remnant issue from 6.9.0.1?

This is related to that change. I will take a look at it this weekend.
