[Qt-creator] undefined reference to vtable for <Class Name> - happens in RC1

I still get this linker error with Qt Creator RC1 on WinXP/MingW.

As soon as a new class added to a project inherits from QObject and uses 
the Q_OBJECT macro the build fails.

Example:

    class ViewAdapter : public QObject

    {

        Q_OBJECT

        Q_DISABLE_COPY(ViewAdapter)

         .

         .
         .


Error message is:


undefined reference to 'vtable for ViewAdapter '


Solving the problem:

- "Clean Project" doesn't help
- MUST unload and reopen the project. After this the build succeeds.
