one thing that's helpful when trying to determine what's causing
warnings like this is to run your program under your favorite debugger
with the environment variable G_DEBUG=fatal-warnings set.  This will
cause your program to exit when it issues a warning, at which point
you can examine what caused the error by using the debugger
