Description
Hi,
This is a sample of a qgis 1.8.0 project using a sample shapefile with 4 values:
0101
0102
0103
0104
I have rendered it using old symbology and
a rendering of
0101 => red
null => green
The result of this rendering is a map with a red polygon and three green polygon: 
When I import this project on a qgis-dev last version it transforms the old symbology (unique value) rendering to a new symbology with a categorized where it applies:
0101 => red
null => green
But when I show the map result it shows ONLY ONE (the RED) polygon: 
:(
It guess this is a real problem when qgis 2.0 will be released and many qgis 1.8.0 projects will be imported.
