If a data-block referenced the same shared data more than once, it used to be written multiple times. This worked out so far, because the written data is always the same. So when reading the file, it doesn't matter which written buffer Blender decides to read on. However, this makes the .blend file look corrupt and leads to memory leaks on load (#125001).
