Wireshark flags a decoding error when decoding the triggerAddressList element
of an ANSI MAP message.

The error displayed is:
triggerAddressList: 1 item
  BER Error: Wrong field in SQ OF

For a test capture file, please see the attachment for bug 1820.

Looking at the OriginationRequestResult in this file, it looks like the problem
is detected in the WIN_TriggerList element, which is present with tag 0x9f 0x82
0x1b and length 14.  This seems to be in accordance with 3GPP2 X.S0004-550-E
Version 1.0.0 Date: March 2004, which allows for the field to be an octet
string consisting of one or more detection point types (TDP-R, TDP-N, EDP-R,
EDP-N), each followed by one octet for each trigger type associated with the
detection type.
