Migration from 7.4 to 7.5 breaks the creation of new projects

I created a new branch to my gitlab hosted project using Eclipse git client.

I can see the branch on remote using git branch -a command.

The branch correctly appears on the commits/branches tab in gilt.

However, the branch is not available in the commits tab, branch dropbox selector.

In the compare tab, I can compare master against the new branch by entering the name of the branch by end.

Finally, the activity on the new branch does not appear on the project activity.

I am running gitlab 7.6.2 installed by hand on a Debian system.
