[Matthieu Baerts <matttbe@xxxxxxxxx>]

It *seems* it's not due to Cairo-Dock because the code has not changed (we don't have this crash on Ubuntu Precise with the same version of Cairo-Dock).
It crashes after having called 'dbus_g_proxy_call' function (this function is called 3 times or more in a thread). Note that I don't have this crash if I use this function in the main loop.
