--- Comment #3 from Jim Young <jyoung@xxxxxxx>  2009-07-31 07:46:38 PDT ---
This is not a bug.

The filter "tcp.flags.reset" can be thought of as a presence filter: 
   "Does the packet have a tcp.flags.reset field?"  

The tcp.flags.reset bit, whether it is set or not, is present in the TCP
header.  

A presence filter doesn't care what the actual value that field contains, just
that it has one.

In comment #2 you used probably the most direct way to find a TCP packet with
the RST bit set.  There are other ways as well (like the filter you used in
comment #1).
