Hmm, at first I thought this was a display filter bug (because I knew of
something related in the display filter code). But I see what you're
talking about, somehow your capturing facility saved 60 bytes of data,
no matter what.

On what OS did you make this capture? And what tool did you use
to make the capture. I see it's a libpcap capture... what version of
libpcap are you using?

thanks,
