Git commit 69eb3f4274da3be99a68dd8a265776dc46820d77 by Sebastian Trueg. Committed on 23/09/2011 at 21:07. Pushed by trueg into branch 'master'. Do not use K_GLOBAL_STATIC for a QObject-based class. This fixes two things: 1. One should never create global static QObjects 2. global static creation is not thread-safe for complex classes.
