That's not weird at all.

If you aren't using "-V", and you aren't using a read filter ("-R"),
Tethereal won't do a full dissection of the packet, and won't execute
the code that would report the error.

That was certainly one of the possibilities I suggested (in fact, it was
the first one in the list I gave), but it might also be that WSP packets
aren't supposed to have Long-integer values with a length of 0 but some
machine is sending them.
