I know. I compared with the verify-output from a working machine. For
my theory ("there are different rpm-packages on the disk than in the
rpm-database") to be right there should be a large amounts of files
with wrong MD5-sums. And there is only a handful for which this is the

get the arguments to that call, because it never finishes (last line
