"Locals and Expressions" view lacks substantial properties for Quick UI project (Qt Quick 1)

1. Start a Creator built on Qt 4.8.5.
2. Create a new Qt Quick 1 UI project.
3. Start Debugging this project and see the properties in "Locals and Expressions" view.
   The Rectangle has a color property and the Text element has a color and a text property.
4. Close Creator.
5. Start a Creator built on Qt 5.1.2 or Qt 5.2.
6. Load the project from step 2.
7. Repeat step 3.
   The said properties are missing from the Items.

Text and color properties should be shown if reasonable. At least Creator should act in the same way, regardless of the underlying Qt version.
