Which version is this? I know some version had an issue with attachments not being properly associated with aggregated stories.

Yes, upgrading to the current version should resolve the issue you are experiencing with the attachments.
Regarding the attributes, that is different situation. It is in fact not the same story that you get out of the aggregated newsfeed as you originally added to the actor feed (mini feed) and thus it does not share the attributes.
The problem accurs when i try to get the storys of the current users friends by using NewsFeedHandler.GetNewsFeed. This i what I do:

Then I get all storeys for friends of "displayuser" like this:
