Bad signatures in XFree86 4.3.0

Hi, I'm am newbie with SuSE 8.0. I downloaded KDE 3.1.1 and XFree86 4.3.0 as rpm-files from ftp.suse.com ftp://ftp.suse.com/ and somehow installed it. Unfortunately too late, I read that it is possible to check the internal signature with rpm -checksig *.rpm The KDE files were OK, but XFree86 4.3.0 files failed. Did anybody notice it too?
