It makes sense to me if it's triggered by inventory actions. It seems to happen much more often with blocks that drop items, especially multiple items. It happens once in almost every vein of redstone I mine (with Fortune), but hasn't happened to me yet with veins of blocks that drop themselves (iron ore and gold ore). I am going to check if Fortune or not makes a difference.
