REVISION SUMMARY
  This method checks whether m_topLevel is not null in a couple
  of places, but misses this one.
  
  p.s. If there are more places where kwin does clear_or_something(); return;
  it could benefit from introducing on_scope_exit and similar tricks - see
  Alexandrescu's 'Declarative control flow' presentation.
