error: unpacking of archive failed on file ...rpm;4a2a2501: cpio: Digest mismatch

Please help me with this problem.

rpm 4.7.0. System: a DIYS linux, everything from sources

4.7.0 was working since may 12.
4.7.0 was linked to nspr-4.7.3 and nss-3.12.2 distributed
with firefox 3.0.9

Until jun 30 when I updated to nspr-4.7.4 and nss-3.12.3.
Always the same error like:
# rpm -U --force bash-4.0-1.i386.rpm
warning: bash-4.0-1.i386.rpm: Header SHA1 digest: NOKEY
warning: bash-4.0-1.i386: Header SHA1 digest: NOKEY

$ rpm -q --dump -p bash-4.0-1.i386.rpm
warning: bash-4.0-1.i386.rpm: Header SHA1 digest: NOKEY
/bin/bash 620928 1241810277 d2533a8f742e68e543304327d7b7e87f \

...
$ md5sum /bin/bash
d2533a8f742e68e543304327d7b7e87f  /bin/bash

I have a chroot directory /media/hda where I
copied an old /bin/rpm (4.4.2.3) and the libs,
installed my own built firefox-3.0.9.rpm (for the nspr and nss)
installed rpm-4.7.0
deleted /var/lib/rpm/*
rpm --initdb
rpm -i bash-4.0-1.i386.rpm works

But in another chroot directory /home/tjoen/cdrom1
I copied the necessary libs:
~/cdrom1/lib $ ls
ld-linux.so.2    libexpat.so.1      libntfs.so.10       librpmbuild.so.0

[in /media/hda]

AAAARGH!

Why the difference?
Please help me

I have tried 4.6.1, same error
Compiled  nspr-4.7.3 and nss-3.12.2, same error.
(That was the version in firefox-3.0.9)
Also strange rendering html-files. <h3>-tag very big.
--nodigest and --nofiledigest don't work here.
Only nspr and nss compiled with firefox-3.0.9
works, and only before jun 30 or in /media/hda

Searched on Google. Not sure others have the same problem.
It looks like Fedora has a special nss.
