incorrect beams in 16th quintuplet

[luis jure]

hello list,

sorry, i guess this must be in the docs somewhere, perhaps it has been
discussed in the list before, but i can't really find a solution...

when writing irregular 16th-note quintuplets (one 8th-note and three
16ths) i get incorrect beaming groups, depending where the 8th note is
placed

the first two tuplets (bar 1) are correct, but their mirrors (bar 2)
have their beams wrong (see attached image). here's the very simple
code:


\version "2.11.42"

\relative c'
{ 
\times 4/5 { f8 f16 f16 f16 } r4
\times 4/5 { f16 f8 f16 f16 } r4
\times 4/5 { f16 f16 f8 f16 } r4
\times 4/5 { f16 f16 f16 f8 } r4

}

\layout{ragged-right=##t}


thanks,

lj
