I've just re-installed the previous version of DBus (1.4.18) and DBus- GLib (0.98) and I still have this crash :-/
This is the backtrace of the crash with the latest version of DBus (1.6.4) and DBus-GLib (0.100) #0 _dbus_watch_invalidate (watch=0x0) at ../../dbus/dbus-watch.c:171 No locals. #1 0x00007ffff032c77d
