D-Bus default limit of replies per connection has been lowered to 128 due to
CVE-2014-3638, see:
http://cgit.freedesktop.org/dbus/dbus/commit/?id=5bc7f9519ebc6117ba300c704794b36b87c2194b
https://bugs.freedesktop.org/show_bug.cgi?id=81053
The limit seems to be too low and causes problems in libnm-glib, that will not
return all NetworkManager connection profiles if there are too many of them
(roughly more than the limit). As a consequence, libnm-glib based clients will
not work properly.
Lets increase the limit in our D-Bus org.freedesktop.NetworkManager.conf
configuration as we had it before.
See also older commit d5b31d55fa that did the
opposite thing (removing the limit because the default D-Bus limit was 8192 at
that time).
