Comment 1 for bug 76264

Forwarded from: https://launchpad.net/distros/ubuntu/+source/libtelepathy/+bug/76264

Binary package hint: libtelepathy-dev

The file:
/usr/include/telepathy-1.0/libtelepathy/tp-helpers.h

Is missing a:
#include <dbus/dbus-glib.h>

Without that, it will have invalid lines after that:
DBusGConnection *tp_get_bus ();
DBusGProxy *tp_get_bus_proxy ();
