LilyPond bug: grace notes, breaks, proportional

Ok, this is the first serious bug i run into in LilyPond. Line/page breaks immediately before \grace notes or immediately after \afterGrace notes when proportional notation is ON makes LilyPond throw programming errors and formats incorrectly: 

\version "2.11.64"
\include "english.ly"
\layout{
   \context{ \Score
      proportionalNotationDuration = #(ly:make-moment 1 34)
      \override SpacingSpanner #'strict-note-spacing =##t
      %\override SpacingSpanner #'strict-grace-spacing = ##t
      %\override SpacingSpanner #'uniform-stretching = ##t
   }
}
{
   \new Voice{
     \time 1/4
     c'4
     \break
     \afterGrace c'4 {g'64}
     \break
     c'4
     \break
     c'4
   }
   \new Voice{
     \time 1/4
     c'4
     \break
     \grace{ g'64 }
     c'4
     \break
     c'4
     \break
     c'4
   }
}
