This apparently caused a test failure on PPC, due to the test in question checking that no logging output occurred:

The problem call is within the GNetworkMonitor code, and it looks like it is due to the constructor for the class not being safe if called outside of the main loop thread. Making sure it is initialised early looks like it will solve the problem.
