I have heard of such cases and it may be down to the fact that the sealant around the window becomes hard and inflexible at low temperatures and the glass is unable to move when it expands. Apparently this is more likely to occur where there has been consistent low temperatures over a number of days. Additionally could there have been a gap in the sealant and moisture was able to get in and freeze thus creating undue pressure on the edges of the glass.
I wonder how this affects our poor northern european cousins though. It is also possible the glass may have been stressed at some point when the boot door was closed against something in the boot.
Having said that I have witnessed the sliding sunroof of a Peugot shatter on a warm day when the drivers door was slammed shut.
Weird thing is that glass is classified as a liquid and has some very strange qualities
