Wireshark · Ethereal-dev: [ethereal-dev] bug ?

[stefan <stefan@xxxxxxxx>]

Hello Ethereal'ers,

I would like to report a fatal error to you:

uname -sr:
Linux 2.2.10

gtk-config --version:
1.2.6

ethereal -v:
ethereal 0.8.5, with GTK+ 1.2.6, with libpcap 0.4, with libz 1.1.3,
without SNMP


When I start ethereal without arguments, load the logfile within the
attachment (irc-stream-1.log - produced with a previous version of
ethereal) and then Start-Capture with Filter: "tcp port 6667" or even
without Filter i get a segmentation fault. The bt of gdb says what's in
the second attachment.

Anyway, you developed a real great software !!! It helps me testing my own
software development, learning "undocumented" protocols from your program.
It *very* useful, keep it up !

One more hint/feature-request. The Hex. Dump is a very good idea, but it
doesnt help without the actual text representation. Maybe it is possible
to have both on one screen, something like:

00 00 00 00 00 00 00 00 00 00 00 00 00    abcdefgh12345
00 00 00 00 00 00 00 00 00 00 00 00 00    abcdefgh12345
00 00 00 00 00 00 00 00 00 00 00 00 00    abcdefgh12345
00 00 00 00 00 00 00 00 00 00 00 00 00    abcdefgh12345

Hope this will help.
