When you mine a block and there are transparent blocks around, the item will sometimes drop into the transparent block and not allow you to pick up the drop.
This is most prevalent with stairs. To pick up the item you must destroy the block that the item fell into.

Pretty minor, yeah, but pretty irritating too. Possibly unrelated, but sometimes when this happens I can't pick up the item at all, even if I dig all around it, relog, etc.
Yes, the items might also fall below placed blocks..
Is this related?
When digging a 1 block hole and not picking up the drop of it, then placing glowstone into it, the drop will hover up one block but be impossible to pick up
Items get stuck in half slabs too.
Edit: spelling and summarization
Yes, and the hover issue is a client/server sync bug it seems, the server knows that the item is under the block but the client renders it on top anyway.
I mostly notice this in Jungles when cutting trees, with all the leaves around, a lot of items fall under the leaves.
Could be fixed by making the items perceive all blocks to be opaque and solid.
Yes, this is quite an annoying little bug.
I've just come across having an item stuck in a sign, I assume it's the same issue.
The situation:
MC 1.4.2 vanilla
I have a custom mob spawner set to spawn items in a SpawnRange of 1, with MaxNearbyEntities 1.
I want to avoid using the item->Pos coordinates to place the item where I want it, as I need to copy the system a lot. Editing the item it spawns is easy, the position is more of a hassle.Simply filling up the area where I don't want the item to spawn will fail often (1/2 or something), the item getting stuck in the blocks, having to dig to get it out. (the bug reported here)
So, I'm using water to move the item to the block I want it in, having water flow first above the spawner, and then down and under the spawner, to pick up items that may spawn on top of the spawner block.
Occasionally (1/50 or something), an item spawns seemingly inside one of the signs that hold up the water. It just floats where the sign is instead of falling into the water, preventing it to be sent to the player and also preventing a new item spawning. Effectively the system fails until the stuck item despawns.
It can be picked up by being near the sign, but I cannot allow the player into the spawning area.
If needed I can provide screenshot(s) and/or a .schematic file.
PS: Application is for an adventure map: it's a shop where you can buy gear with xp. I'd use command blocks with give, but I can't use enchantments and names that way.
For now I'll stick with the 1/50 chance of failure, and I'll use the Item->Age property to make the items despawn after 1 minute instead of 5.

Anyone can loose a diamond because of this glitch
