[leafnode-list] Very nice backtrace -- anybody interested ;-)

[Matej Cepl <mcepl@xxxxxxxxxx>]

Hi,

when created my testing package of leafnode2 for RHEL5 (just
RedHatification of the original spec file), I got this backtrace when
running /usr/sbin/fetchnews -vvvv (unfortunately, no core and thus no
backtrace):

-sh-3.1$ /usr/sbin/fetchnews -vvvv

Any ideas, what's going on, please?

Best,

There's a long-standing bug relating to the x86 architecture
that allows you to install Windows.
