Ah thanks for the file, I see what you mean now. Think is, that kind of transform is not possible in Object mode (besides along the object's local axes), you'll have to do it in Edit mode if you want a proper mirroring along an arbitrary axis. Thats not a bug, just a usual limitation of Object mode> Thanks for the report anyway.
