------- Comment #1 from stephentfisher@xxxxxxxxx  2007-11-21 17:29 GMT -------
Thanks for bringing this to our attention.  This problem is being caused by an
asynchronous DNS lookup library we use called adns, which lets Wireshark do DNS
lookups "in the background" and get the results later during the display of
further packets.  The ADNS web site
(http://www.chiark.greenend.org.uk/~ian/adns/) lists IPv6 support as an
upcoming feature, but I'm not holding my breath for it to come as adns isn't
updated very often.

The only way to get around this problem right now is to disable adns when
compiling (--without-adns on the configure line), but unfortunately capturing
and loading of capture files may be slower as DNS lookups will be blocking
every time a new packet arrives/is displayed until the lookup is complete.

We need to come up with a fix to this -- either pressuring the adns maintainers
to support IPv6 or by implementing our own asynchronous DNS lookup library in
Wireshark.
