The problem is that dispatch is called recursively, and it isn't meant
I thought this wasn't possible with the GLib main loop since the
dispatch stuff isn't G_SOURCE_CAN_RECURSE. However, I see that the IO
handler also calls dispatch.
If you can reliably reproduce the bug, try this: remove
dbus_connection_dispatch() calls from io_handler_dispatch in
I can imagine ways to just remove the no-recursive-dispatch restriction
but they all seem sort of complicated, so if the simple fix works we
should go with it for now I think.
