the crash appears to be caused by a <flowSpan> element that had a null value where it was expecting text :
if I take the element : <flowSpan id="flowSpan10489" style="font-weight:normal;-inkscape-font-specification:Gill Sans MT"></flowSpan>
and replace it with : <flowSpan id="flowSpan10489" style="font-weight:normal;-inkscape-font-specification:Gill Sans MT">T</flowSpan>
then the crash disappears, file attached.
