After reproducing the bug, I discovered the error can be resolved if each object (other), is placed slightly differently from each other, so that the vertices, don't align.

While the idea of modifiers is non-destructive workflow, the issue still persists before and after you apply the modification to the object.
A temporary solution would be to recreate the existing object as a NEW mesh, when you apply a boolean, and then link all existing properties to the NEW mesh automatically.
Internally of course, without the user requiring any extra work.

Ultimately though, the issue should be resolved, just as with versions 2.60a and before. :)

Which means, a minor workaround for now, would be scaling each individual object (other), by 1 unit, resolves the issue.
