regression: a multipolygon shapefile fails to render

On QGIS master, the attached shapefile fails to render its single multipolygon properly. Instead of rendering all parts of the single multipolygon, the rendering process stops halfway, failing to draw most of it (including, if I'm not wrong, its principal part).

Steps to reproduce:
  1. Open QGIS, and create a blank project
  2. Add the attached shapefile layer
  3. You'll notice most of the canvas will be blank, with the exception of some small polygon parts at the bottom of the canvas

If you open the layer property window and disable simplification, the whole multipolygon is drawn properly. This is a regression that appeared following the geometry improvement commits.
