[Zope] images last-modified bug?

Hi, I read sometime ago of a bug in zope not sending images header last-modified, which cause browsers to always get images from zope not using the browser's cache. I'm seeing some different behaviour in my site statistics since I upgrade from 216 to 222, and I think it could be related with this image problem. I search in HISTORY.txt but I cant find nothing saying If the bug really existed and if it was fixed. Any help?
