Wireshark · Ethereal-dev: [Ethereal-dev] Ethereal still segfaults on startup

[Joerg Mayer <jmayer@xxxxxxxxx>]

Hello,

I've still the problem that Ethereal segfaults on startup. I've built a
less optimized version in order to get a useable stack/backtrace. It looks
like this:

(gdb) run

This doesn't look too helpful. Ideas anyone?

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
