Segfault bei apt-get update

[Andre Berger <andre.berger@web.de>]

Ich habe heute ein mir neues Problem auf meinem Sarge/PPC mit wenigen
backports-Paketen (lighttpd, freepops, lsb-base) bemerkt:

# cat /etc/apt/sources.list
deb http://mirrors.kernel.org/debian/ stable main contrib non-free
deb-src http://mirrors.kernel.org/debian/ stable main contrib non-free
deb http://security.debian.org/ stable/updates main contrib non-free
deb-src http://security.debian.org/ stable/updates main contrib non-free
deb http://www.backports.org/debian/ sarge-backports main
deb-src http://www.backports.org/debian/ sarge-backports main

# apt-get update
[snip]
Hit http://mirrors.kernel.org stable/non-free Release

Was kann man da machen?
