Package: libc6 Version: 2.3.6.ds1-7 Severity: serious Hello,
Upgadring my etch system this morning, I saw that iconvconfig segfaults:
zsh: segmentation fault iconvconfig
Little debug info:

0x0026a733 in tfind () from /lib/tls/libc.so.6
FWIW, my kernel is Debian 2.6.18 recompiled with exec-shield patch, so
it might come from that. With kernel 2.6.17-2-686 I don't have this problem.
However, I suspect that this is a bug from iconvconfig anyway.
Do not hesitate to ask for more debug output if needed.
Cheers,
