'Locals & Expressions' bug with vectors of classes with static member(s)

In certain cicrumstances (see the "main.cpp" file included for a very simple repro) the "Locals and Expressions" panel fails to display items in an array :

The problem seems to come from a static member in the String class. When removing the member, the problem doesn't happen, and we can correctly browse the content of the array.

I've located the problem in the "dumper.py" file. It's in the "extractField" member of the "Value" class: when we reach the static member, "field.bitpos" is "None". And since this value is then divided by 8 to get the position in bytes, we have an exception, which result in the "<not accessible>" problem.

A quick and dirty fix was to patch dumper.py and check for "field.bitpos" (around line 3037 with my version of Creator) When None, I just ignore the part dealing with it. It works fine, but I can't browse "m_null_string", so the fix is not complete

Edit: after the 4.3.1, it no longer displays <not accessible> but instead the address of the static is the same as the address of the instance, which is incorrect.

And in my opinion, even worse : at least when I see <no accessible> I know something's wrong, whereas now I see something, and if I'm not careful I won't notice that it's erroneous. Debugging is one of the most important thing in development, so trusting what my debugger shows is pretty critical.
