Wireshark-users: [Wireshark-users] Wireshark decode complaining about Malfromed packet - (bogus,

Hi,
 
I was trying to capturing DNS packets using Wireshark, and it gave errors about bogus payload length.
 
For example in the Frame 23 in the dump:
 
  IP length is 324 bytes
  UDP length is 304 bytes
 
However there is a complaint about bogus payload length 49 : Bad length value 304 > IP payload length
 
Any idea why this is coming eventhough the entire packet was captured.  The bytes beyond 49 bytes in the payload are treated as Ethernet trailer packets.
 
Thanks,

Ramji
