beaming failure

[Boros András]

Hi Lilypond,

Please have a look at the following sample with four identical quarters.
Result: Whereas the beaming of the 2nd and 4th quarter is ok, this is wrong at 
the 1st and 3rd quarter.

\score { \notes {
\key bes \major
\time 4/4
\clef treble
[g'8  \times 2/3 {g''16( f''16 )g''16}] 
[g'8  \times 2/3 {g''16( f''16 )g''16}]
[g'8  \times 2/3 {g''16( f''16 )g''16}]
[g'8  \times 2/3 {g''16( f''16 )g''16}]
} }

Lilypond version: 1.4.12.jcn5
I downloaded the binary release.

Machine:
GenuineIntel
Pentium II 
Intel MMX Technology
192 MB RAM

Operating system:
MS Windows 98 
4.10.1998
