SLED10SP2 Online Update signing key error

[EnviroTO]

I did a clean install of SP2 but registering online update sources fails with:

Refresh Failed: Failed to parse XML metadata: Key verification for '/repodata/repomd.xml (file:/var/cache/zmd/web/files/nu.novell.com/repo/$RCE/SLED10-SP2-Pool/sled-10-i586/)' failed 'SuSE Package Signing Key <build@suse.de>' (A84EDAE89C800ACA)

I don't remember a "Pool" update source before but I cant seem to remove it completely from rug either because it shares the same server as "Updates". No key issues on other sources.
