Ah, I can reproduce on my x86 when I tell glib to make errors fatal:

G_DEBUG=fatal-warnings ./virsystemdtest

and it looks like the problem is that g_dbus_connection_call_sync() 
consumes the message parameters so transitively virGDBusCallMethod() 
consumes the mssage (the last argument) and therefore we should not 
unref it afterwards. I'm testing a fix as we speak.
