Comment #4 on issue 1772 by address@hidden: Completion_rest_engraver fails  
with fractional rests
http://code.google.com/p/lilypond/issues/detail?id=1772

Regarding the original report: I don't think it is the job of any  
completion engraver to split up input with a scale factor into notes with  
different scale factors.  That's a problem with more variables than  
information, so LilyPond can't pick a sensible solution.  So don't use  
scale factors when you don't actually want to scale note values (like  
tuplets would do) but rather shift the onset of the next note around.  Not  
when using completion engravers (and actually not when producing Midi, even  
though the results for notes will be worse than for rests).

Once we realize that nothing but producing notes/rests with the _same_  
scale factor makes sense for a mechanically chosen solution (and that's  
what one would expect with \times as well), it is clear that the r1*6/4  
case is not something that completion engravers can sensibly deal with.   
Write { r1 \skip 2 } if that's what you mean.

We don't want to employ a Diophantean equation engraver that picks out one  
of possibly several integral solutions from a linear equation equivalent to  
a line through a grid.  So the current output is a visual approximation of  
how things are going wrong given an impossible task.

I lean towards considering issue 3560 valid and marking this issue here as  
invalid on Oct 2 without previous compelling arguments to the contrary.
