1988 924s Rear Hatch Exploded???

I am reading online that on occasion the glass on the rear hatch can explode, does anyone aside from me have any experience with this? I came home to glass everywhere with no reason. some seem to say its the result of the glass delaminating and others say its the result of a latch failure and other other say its just sunlight??? can anyone confirm?

also, does anyone know where I can get a hatch? it seems like no one is willing to ship them.
