Wireshark · Ethereal-dev: [ethereal-dev] NBNS and SEG fault

[Gregor Glomm <gg@xxxxxx>]

Hi,

here is a NBNS packet from me. This is not a packet from a windows
client, but i
think there is no error in this packet.

But when i expand all fields and go up and down in this fields i get
a SEG fault. 
Here it was the field (Time to Live) in the NBNS frame but i think 
it can be anyone else.
I have set the permisions to "chmod 600 NBNS.Error".
This error don´t occor every time with this packet.
Pleas try the trace and help me.
Here is the bt from gbd.

Gregor
