Sibelius crashes with a "division by zero" error when importing a MusicXML file if the MusicXML originated with a Finale score in which the Patterson plug-in "Beam over Barlines" had been used to split a beam over a barline which is also a system break or page break.
Sibelius should not crash, no matter how strange the MusicXML might be.
(a) a sample Finale 2014 file with such a split beam over a system break;
(b) the resultant MusicXML export from Finale, which causes Sibelius to crash while importing.
