Locals view goes berserk on QThread

1. Open simple.pro from Creator's repository.
   It's in tests/manual/debugger/simple/simple.pro
2. Uncomment the call to qthread::testQThread();
   It currently is in line 7307 of main.cpp
3. Place a breakpoint in qthread::Thread::run.
   I had it in line 4308 of main.cpp:

   if (m_id == 2) {
   

4. Debug the application.
   It will hit the breakpoint. Everything looks fine so far.
5. In Locals view, expand "this".
   The displayed values will quickly change continuously. It looks like the debugger is rushing through all started threads.

The Locals view should only display the values of the one thread where the debugger stopped.
