in some cases <tupletSpan> elements are tripled. All carry the same @startid but only one of them a proper @endid.

<tupletSpan xml:id="m-41" num="3" num.format="count" numbase="2" startid="#m-39"/>
<tupletSpan xml:id="m-43" num="3" num.format="count" numbase="2" startid="#m-39"/>
<tupletSpan xml:id="m-45" endid="#m-44" num="3" num.format="count" numbase="2" startid="#m-39"/>
<tupletSpan xml:id="m-51" num="3" num.format="count" numbase="2" startid="#m-49"/>
<tupletSpan xml:id="m-53" num="3" num.format="count" numbase="2" startid="#m-49"/>
<tupletSpan xml:id="m-55" endid="#m-54" num="3" num.format="count" numbase="2" startid="#m-49"/>

There are more problems that are probably related. See the following conversion:

If the first thing under the beam is a tuplet, then we get a wrong <tuplet> element and duplicated notes and beams, otherwise we get duplicated <tupletSpan>s. Alas, still some work to do...
