Hi,

I just came across this issue. It seems that users other than the superuser can not view version history from within AdminCentral.

Steps to reproduce:

1. Log into http://demoauthor.magnolia-cms.com as superuser
2. Go to Documents/demo-project/img/logos
3. Right click on magnolia-logo and choose Delete, then click Ok in the dialog box that appears
4. Right click on the magnolia-logo again, and choose Versions
5. In the Versions dialog that opens, you should see a version that you can restore to. Close the window without restoring.
6. Log out as superuser, then log in as eric
7. Go to Documents/demo-project/img/logos
8. Right click on magnolia-logo, and choose Versions
9. Note that there is no version information displayed, and eric can't restore a version

The same thing occurs when activating content. Users other than superuser aren't able to view Versions.

Let me know if you have any other questions.

Cheers,
Matt
