[Qgis-user] Shape file points not appearing in 2.0.1

[Eureka Modélisation]

Hi all,

I follow this thread with interest because I have a layer with exactly
the same behaviour, behaviour which also appear in the transition from
QGIS 1.8 to 2.0.

Unfortunately, I don't find any point with all NULL attributes in this
layer.

You can find the layer here : https://db.tt/1kPuqEvd (a bit big, sory !)

Thanks for any help
