audtool segfaults in g_dbus_connection_close_sync() occasionally
Most of the crashes in the attachment happened to audtool called by my application, not manually. But today when I run `audtool help` from terminal, it displayed the help message and segfaulted. I don't know if versions other than 3.10.1 and 4.0.1 are affected, because my coredumpctl list goes back less than five months.

audtool is one of the most common programs in my coredumpctl list. audtool runs only for a very short time, though many times every day on my system. So this launch frequency could be a reason it crashes relatively often. Or perhaps it's something about how audtool is built.

Well, the backtraces are all identical, and all within g_dbus_connection_close_sync(). I suspect there is a bug in that function -- maybe related to it being called in an atexit() handler.
To get to the root of this, someone will have to find a way to reliably reproduce it, and then spend some time debugging that call tree in GLib. I don't have the time to do this myself.
