I would say completely common,mine completely separated last night. There is only one little bracket screwed into the wall and some staples holding it together. The bracket has no stud behind it. The 2 screws that go into the wall are only going into a thin piece of panel.
I plan on taking a trip to the hard ware store,making a new longer bracket that goes to a wall stud. Also in going to screw and glue the panel to the dinette.
