I downloaded the installer files again from the ftp site and have done a
new test with the same result.

After some debugging at the system with the installer running I found
that in the shell script
/usr/lib/debian-installer/retriever/net-retriever 'gpgv' is called (line
96ff). When I call this command
at the running system I get the following output:
~ # gpgv --status-fd 1 --keyring /usr/share/keyrings/archive.gpg
--ignore-time-conflict /tmp/net-retriever-1558-Release.gpg
/tmp/net-retriever-1558-Release
gpgv: Signature made Sat May 14 02:23:49 2011 UTC using RSA key ID 473041FA
[GNUPG:] ERRSIG AED4B06F473041FA 1 2 00 1305339829 9
[GNUPG:] NO_PUBKEY AED4B06F473041FA
gpgv: Can't check signature: public key not found

The start of file /tmp/net-retriever-1558-Release contains the following
lines:

Origin: Debian
Label: Debian
Suite: testing
Codename: wheezy
Date: Sat, 14 May 2011 02:23:28 UTC
Valid-Until: Sat, 21 May 2011 02:23:28 UTC
Architectures: amd64 armel i386 ia64 kfreebsd-amd64 kfreebsd-i386 mips
mipsel powerpc s390 sparc
Components: main contrib non-free
Description: Debian x.y Testing distribution - Not Released

So, the problem seems to be that the wrong Release file is downloaded by
the installer.
