Removing a source block of water/lava with a bucket can cause the game to add water/lava buckets in to your inventory

Affects versions 1.5, and 1.4
The bug: When you try to remove a source block of water/lava with a bucket, water/lava buckets will begin to appear in your inventory. This isn't supposed to behave like that. In the older versions, this bug was never present, and now, the bug is kinda anoying. Up to version 1.6, this isn't fixed yet.
