tp_connection_manager_new() takes a manager_filename parameter: http://telepathy.freedesktop.org/doc/telepathy-glib/telepathy-glib-connection-manager.html#tp-connection-manager-new This seems to be the name for the cache of connection manager properties. If so, that should be documented. I guess that this should be optional, meaning that either a default file will be used, or no cache will be used. Maybe it already is. If so, that should be documented.
The #TpConnectionManager:manager-file property had an associated docstring stating that it can be NULL, but unfortunately all the property docstrings in this file mistakenly have two colons, so gtkdoc ignores the docstring and introspects the property instead, yielding less useful documentation. I've fixed this and clarified the documentation, pending review.
