Stepping on closing bracket of method shows garbage in the Locals and Watchers

Breaking on the closing bracket of a method shows garbage in the custom dumpers.

How to reproduce

Set a breakpoint on the closing bracket of e.g. creator/tests/manual/gdbdebugger/simple/app.cpp
Run debugger until it stops there
In my case Locals and Watchers claims that vector has 4 items, while list is not in scope
