My fault - there I detected it first time. I'm a bit EHEADEVERYWHERE at
the moment, sorry.

Again my fault. It crashes on MacOS X (X11 environment), Ubuntu and
Solaris, too.
It's not related to NetBSD.

If it wouldn't dump core on 'use Wx qw(:allclasses);', would be enough.
I don't want request a magical fix what might bring Wx working without
an output device, but a core dump leads me to the assumption, that
something is going heavily wrong.
