Co-authors not allowed to save updated posts

[jroselarsen]

Since 3.6.0 it's not possible for co-authors to save updated posts.
Only the primary author can do this.
Has worked prior to this version.
Restoring the plugin to 3.5.15 makes it work again.
Setting "allow editing of others" using Capabilities, works.

But that is NOT what we want.

This goes for the latest 3.6.3 version too.
Any solutions???

In our environment, Co-Authors (not the primary/first) are able to edit Posts just fine with 3.6.3.

Can you try providing some more details about the situation so I can try to reproduce? For example, the user roles of those involved.
