If the checksum is wrong wireshark will not try to do reassembly under the
presumtion that a damaged frame is of no use(as would an application).
As most modern NICs do TCP checksum offloading e.g the checksum is calculated
on the board. The checksum will be zero on outgoing frames as libpcap will
"see" the packets before they ar sent to the NIC. I'm not sure about incomming
frames. 

In short the preference "Validate the TCP checksum if possible" should be off
in most situations and I think it's the current default however if you upgraded
from previous versions your original preferences would have been keept.

I'm closing this bug as this is the expected behaviour.
