Proposed patch that fixes this issue

This patch has been made based on the capture file provided. 

The problem is, that the subdissector calls the function `tcp_dissect_pdus()'
and reports that the last PDU has more data than the acutal packet contain. 

This is normally not a problem when a PDU spans over multiple segments and the
next segment is available.

But it causes Wireshark to crash when it attempt to mark the amount of hex-data
which is actually not available in the provided capture file, as it contains
just one packet.

I asked for another packet capture where two segments are included with a
spanning PDU. But got no reply yet. Therefore I don't know if it works well in
such a case.

I'd appreciate if someone could revise this patch and/or test it.
