Error exposed byba49345705. Code just assumed that the tree-element pointed to a real ID, but this is often not the case, and the ID pointer contains completely different data. E.g. beforeba49345705, it would be a pointer to one of the `Main` listbases, so this code would have undefined behavior. Now the pointer is null for elements in the "Current File" element, causing a null-pointer dereference rather than undefined behavior (that just happened to virtually always result in the intended code path).
