Completion_heads_engraver / Score.timing = ##f

Hi all,
the following example fails to compile because of an endless 
loop in misc.cc:21. The function intlog2 is called from 
Duration.cc with zero as argument.
This occurs only if the "untimed" part is longer than a 
conventional measure >and< some note follows after switching 
back to normal timing mode.
At the moment I don't have enough time for further investigating.

\version "2.13.0" 
 
foo = \relative c'' { 
 \time 4/4 
 \set Score.timing = ##f 
 a2 d d 
 % a2 d This works
 \set Score.timing = ##t 
 a4 % Removing that note works too
} 
 
\score { 
 \new Voice \foo 
 \layout { 
  \context { 
   \Voice 
   \remove "Note_heads_engraver" 
   \consists "Completion_heads_engraver" 
  } 
 }
}

Cheers,
Michael
