If a shapefile is indexed using ''shapeindex'' with srs ''+proj=latlong +datum=WGS84'' and during rendering it needs to be reprojected to google mercator ''+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs +over'', leftmost and topmost features will not be rendered. If shape.index indexfile is removed, all features are rendered.

Strangely, this doesn't happen for the first test case...

I've attached shapes and XMLs that can be used to test this behaviour.
