beam bug?

[Stan Sanderson]

I believe I saw this previously reported, but haven't found the  
discussion (or a temporary resolution).

An 8th followed by a 16th rest and 2 or more 16th notes results in  
the bar extending to the left of the first 16th note. In the  
following snippet, the first group is logical; the beam fragment is  
necessary to interpreting the timing of the 16th note. The second  
group also has the fragment of beam, but in this case it is  
unnecessary and out of place.

\version "2.11.34"
\score {\new Staff {
\relative c' {f8[ r16 f] f8[ r16 f f]}}}
\layout {ragged-right=##t }

If there is a work-around, I would be grateful for it.

Thanks-

Stan
