I wouldn't actually call it a bug.  It happens because lily now places 
objects around text based on the actual shape of the text itself.  However, 
the whiteout is purely a box, and so doesn't follow the same shape.  Simple 
fix:

\layout {
\context {
\Score
\override TextScript.whiteout = ##t
\override TextScript #'vertical-skylines = #'()
}
}
