I think I have a fix for the problem, I'd like to test it. Could you
please send to the list (or to me directly)  few of those packets that
triggered the errors and  the one that caused the crash .

I notice that the cap file you are dealing with is huge.

To get to know the frame number of the packet that caused the crash you can do:
(gdb) frame 4
(gdb) p pinfo->fd->num
(gdb) quit

disable http

$ echo http >> $HOME/.ethereal/disabled_protos

save the packets

$ tethereal -r x.cap -w crasher_packets.cap -R 'frame.number ==
3215557 || frame.number == 2947084 || frame.number ==
the_crashing_one'

restore http

$ ex -c '$d|wq'  $HOME/.ethereal/disabled_protos


Thanks
