Exploding Glass Oven Door

An investigation has just been completed into the cause of the failure of an oven glass door. The situation was such that the owner had started the self cleaning feature of the oven. After a short while, the owner heard popping and cracking noises coming from the oven. Upon investigating, the owner found that the interior door glass pane had shattered. It appeared that a control malfunction caused the oven to overheat and expand the glass beyond its’ railing space. The result was the failure of the glass. The glass was part of a Kitchen Aid built-in oven, model # KEBS177SWH02. Has anyone experienced a similar failure? A photograph of the oven door is shown below.
