Overriding OttavaBracket.text fails for unknown reasons. Has to be
done after/before-line-breaking.
It fails for \propertyOverride Staff.OttavaBracket.text as well, which
prevents alterBroken from working.

\version "2.19.32"

%% does not work
\relative {
  \override Staff.OttavaBracket.text = #"foo"
  \ottava #-1
  c1 d
}

%% does not work
\relative {
  \propertyOverride Staff.OttavaBracket.text "foo"
  \ottava #-1
  c1 d
}

%% works
\relative {
  \override Staff.OttavaBracket.after-line-breaking =
    #(lambda (grob) (ly:grob-set-property! grob 'text "foo"))
  \ottava #-1
  c1 d
}

%% works
\relative {
  \override Staff.OttavaBracket.before-line-breaking =
    #(lambda (grob) (ly:grob-set-property! grob 'text "foo"))
