There seem to be some issues reported in the bug tracker and on the
list with blocking in another thread. Two possible solutions are 1)
debug those issues and send a patch or 2) use a main loop instead
(with dbus_pending_call_set_notify() for example as you say) and only
use the thread to do your work, don't use the thread to interact with
