gdp: Fix Timmeke Waymans bug.
Original commit message from CVS: 2005-10-13 Andy Wingo <wingo@pobox.com> * libs/gst/dataprotocol/dataprotocol.c (gst_dp_packet_from_caps): Fix Timmeke Waymans bug. (gst_dp_caps_from_packet): Make sure we pass a NUL-terminated string of the proper length to gst_caps_from_string. There's a potential for, before this fix, that this could cause someone connecting over the network to cause a segfault if the payload is not NUL-terminated.
