programming error: when \break used before \grace or after \afterGrace in combination with proportional notation

Hello All,
After trying for hours to figure out why my LilyPond score was generating programming error messages on compilation, I finally found the culprit and was able to come up with a pair of minimal examples generating the errors. I searched the mailing lists for solutions to this, but I found no posts of this specific problem, so I guess this is new.
The problem seems to be occur when combining three things: 1. proportional notation: proportionalNotationDuration = #(ly:make-moment 1 34) \override SpacingSpanner #'strict-note-spacing =##t
2. \grace or \afterGrace notes 3. \break or \pageBreak immediately before \grace or immediately after \afterGrace notes.
The two errors I get are: "programming error: bounds of spanner are invalid"
and "programming error: No spring between column 1 and next one
continuing, cross fingers"
If I remove the strict-note-spacing = ##t assignment, everything works fine. Minimal code examples are included here, together with the LilyPond output.
Any ideas how this can be fixed or how to go around it? Is this a bug?
Many thanks,
V!ctor Adan.
PS Since this seems like a bug, I'm sending to the bug-lilypond mailing list too, just in case.
