snnewgroup: Segmentation fault on ppc systems

Hi!

I just tried to install sn on my iBook (G3) running Debian (I wanted
to use the binary installed by "apt-get install sn"), but snnewgroup
segfaults when I try to create a group, so I recompiled sn with
debugging symbols and started it through gdb:

,----[ gdb running snnewgroup ]
| (gdb) set args gmane.network.sn news.gmane.org 119
| (gdb) run
| Starting program: /usr/sbin/snnewgroup gmane.network.sn news.gmane.org 119
| 
| Program received signal SIGSEGV, Segmentation fault.

If you need more information, tell me and describe me how to get
it. :) I don't get this error on my x86 box.
