Git commit fde0381bb1852793c4991def246b8bc0114e359d by Martin Gräßlin. Committed on 24/04/2012 at 21:10. Pushed by graesslin into branch 'master'. Fix regressions related to stacking order changes The change to have stacking order containing Toplevel inestead of Clients (431aad6d6994695e72697fcc3299ec2cb6f0684e) introduced possible crashers as recognized in: http://git.reviewboard.kde.org/r/104519/#review12714 This change fixes these issues by adding missing null pointer checks after casting to Client.
