Checked in (although I had to apply some of the changes by hand, as the
the current version, as of when I checked it in, was 1.18).

You don't prevent it, you make the dissector handle it.

Ethereal supports reassembling packets that require more than one TCP
segment; I've added code to the COPS dissector to handle that.  The
current CVS dissector reassembles that request and displays it in frame
12.  You have to enable the "Allow subdissector to desegment TCP
streams" TCP preference, as that's off by default; there's also an
option to enable desegmentation of COPS (both options have to be
enabled), but that's on by default.
