Yes, I think these may be related. Also see the post 1 October 2007  
by <address@hidden> in the LilyPond User mailing list, "odd  
beaming in tuplets", where it happens for quintuplets.

I thought it might not be possible to resolve it for all cases, as  
strictly speaking, the beaming is also a suggestion of a musical  
logical structure, that may be communicated by accents in some cases.  
For example, in issue 11, the beaming suggests that the triplet is  
divided into two equal parts, which may be possible, but not the  
normal thing. For n-tuplets, it may depend on the intended musical  
context. The situation is then similar to that of complex meters.  
[For example, Hindemith, "Elementary Training for Musicians", p.  
166b, advices against writing out quadruplets as a series of dotted  
notes, as it destroys the musical logical structure. I think  
therefore that this logical structure maybe must also be used to  
achieve correct beaming, too. Perhaps LilyPond just translates it  
into fraction values first, and then does the beaming, or something.]

So perhaps a general mechanism, with a good, easy to use user  
interface, is needed.
