Did your compiler or presubmit script raise warning if missing?  I think you can
just omit this empty destructor but not 100% sure.

clang complains that classes that are ref-counted should have explicit
destructors.

optional:

!button_index

is more common in chromium.

[Jun Mukai, 2014/02/20 19:04:20]

or DCHECK_EQ(0, button_index)
Since this notification has only one button, the button_index should be 0
always.

Done.
