graesslin added a comment.


  Now I have the warnings again:
  
    /home/martin/src/kde/workspace/kwin/tabbox/tabboxhandler.cpp: In member function ‘QModelIndex KWin::TabBox::TabBoxHandler::nextPrev(bool) const’:
    /home/martin/src/kde/workspace/kwin/tabbox/tabboxhandler.cpp:465:34: warning: ‘model’ may be used uninitialized in this function [-Wmaybe-uninitialized]
                 row = model->rowCount() - 1;
                       ~~~~~~~~~~~~~~~^~
