Can't change display of QByteArray

1. Have a project which contains the following lines:

           QByteArray ba;
           ba += "Hello";
           ba += '"';
           ba += "World";
           ba += char(0);
           ba += 1;
           ba += 2;
   

2. Configure this with a kit using MSVC2010.
3. Set a breakpoint after the said code, let the debugger run up to there and check the contents of the Locals and Expressions view.
   With Qt 4, Creator displays "Hello"World", with Qt 5 it displays "Hello"World..."
4. Right-click on the value and select "Change Local Display Format..." -> "Show Unprintable Characters as Octal" from the context menu.
   Nothing will change.

I have expected to see something like "Hello"World\000\001\002". If it not possible to change the display format for some reason, this part of the context menu should be disabled.
