There is a DBusList* member of BusTransaction named "connections", while its getter function bus_transaction_get_connections() returns context->connections which in fact is a BusConnections pointer, this is quite confusing. Because this is what bus_context_get_connections() returns. This patch call out to bus_context_get_connections() directly and remove the then unused bus_transaction_get_connections(). https://bugs.freedesktop.org/show_bug.cgi?id=71597 Reviewed-by: Simon McVittie <simon.mcvittie@collabora.co.uk>
