Probably something has called dbus_shutdown(), which is basically never
correct to do from a shared library or loadable module (because a shared
library cannot guarantee that some other shared library isn't still
using libdbus), and rarely correct to do at a time other than the end
of main(). If you put a debugger breakpoint on dbus_shutdown, it would
confirm whether that guess is correct, and if so, who is calling it.
