This has been a problem for me through multiple Ubuntu releases and laptops IIRC. Once in a while, the screensaver does not manage to lock the screen before the computer is suspended or hibernated. To be sure, the screen must be locked manually before suspending. Feels like a race condition problem during suspend.
