I consequently happened to have all items from a chest moved to my inventory while I was quickly Shift clicking them. It really looked like a Loot-all hidden feature being activated.
Similarly, once all items hoped from hot-bar to my inventory – again during Shift clicking.
So far, I haven't played multiplayer to see if it happens on bukkit as well.
The minecraft wiki doesn't say anything about such a feature.
Is that a bug? If not, how do I trigger it intentionally?

Well there is currently no such feature that allows you to move all items of different types from your chest to inventory. At least, in vanilla Minecraft.
However, there could be a reason for this "phenomenon" occurring. Accoding to the Minecraft wiki on inventory, it states that:
In addition, it states in the Minecraft wiki for Chests:
To put this into a scenario, if you have a chest entirely filled with ONLY iron ingots, ALL the iron ingots will be transferred to your inventory is you were to ⇧ Shift and double-click one of the IRON INGOT STACKS.
However, if there were blocks of sand mixed up with the ingots, and you were to ⇧ Shift and double-click a stack of IRON INGOTS, all the iron ingots and ONLY the iron ingots will move into your inventory, leaving the sand behind.
