Thanks, Axel.

1. rebuilddb is the 1st thing I tried (before posting my problem). I 
just run strace on it - it died with

2. I backed up my /var/lib/rpm; dumped and restored Packages. Then I run

rpm -qa
error: rpmdbNextIterator: skipping h#    1351 Header V3 DSA signature: 
BAD, key ID db42a60e

the same with --nosignature runs ok, but I have 2 err msgs:

error: rpmdbNextIterator: skipping h#     128 blob size(3768): BAD, 8 + 
16 * il(17) + dl(3456)
error: rpmdbNextIterator: skipping h#     117 blob size(3192): BAD, 8 + 
16 * il(17) + dl(3456)

and another attempt to rebuilddb:

sudo rpm -vv --rebuilddb

And below are all my signatures:

rpm --nosignature -qa gpg\*
error: rpmdbNextIterator: skipping h#     128 blob size(3768): BAD, 8 + 
16 * il(17) + dl(3456)

gpg-pubkey-66534c2b-3e60b428
gpg-pubkey-897da07a-3c979a7f

And I don't see freshrpms, newrpms or Dag's signature there.
Should I remove all these signatures? or?
Any ideas, hints?

Thanks in advance,
Alex Kruchkoff
