Lost permissions after upgrade from stable6 to master

[PVince81]

Steps to reproduce:

1. Check out stable6 (4bc0919)
2. Set up ownCloud from scratch (test with MySQL)
3. Upload a few files into a subfolder
4. Check out master (ecc41fe) and git submodule update
5. Run the upgrade
6. View the file list in the web UI

Expected result

Upload button is visible
The database table oc_permissions should not exist.
The table oc_filecache has its permissions column must contain the permissions.

Actual result

Upload button is missing.
Permissions are set to zero.
The database table oc_permissions still exists.
The table oc_filecache has its permissions column filled with zeroes.

Versions

Upgrade from stable6 to master.
DB: MariaDB 5.5.33
PHP: PHP 5.4.20 (cli)

Same issue with sqlite.

There is something suspicious in the logs:

{"reqId":"53972653a0437","app":"PHP","message":"file_get_contents(\/appinfo\/info.xml): failed to open stream: No such file or directory at \/srv\/www\/htdocs\/owncloud\/lib\/private\/app.php#535","level":0,"time":"2014-06-10T15:37:56+00:00","method":"GET","url":"\/owncloud\/core\/ajax\/update.php?requesttoken=bf2cedd3b0219171adb6"}

Not sure if that could break the upgrade.
