member "data" of QVariant not accessible

1. Open a project and configure it with a kit using a MinGW based Qt.
2. In the project, use the following lines:

   QList<int> list;
   list << 1 << 2 << 3;
   QVariant var;
   var.setValue(list);
   

3. Set a breakpoint after this lines and let the program run into this breakpoint.
   In Locals and Expressions view, Creator will display "var" and its member "data", but the latter is marked as "not accessible". "list" is being displayed correctly.

Since Creator correctly detects a QList inside "var", could it display the contents of the list?
