 1. Take a shape-file with an attribute of datatype real.[[br]]
 2. Open Layer Properties/Symbology[[br]]
 3. Choose unique value[[br]]
 4. Classify attribute of datatype real[[br]]
 5. Legend will updated with the classification[[br]]
 6. Layer disappears from canvas[[br]]

 I can reproduce this behaviour only with shape-files and with attributes
 defined as real. Postgis Layer work fine.
