Rpm DB problems

[Luca Da Col]

Hi everybody, 

I just come to install a new package with rpm -Uhv, but unfortunately
nothing has been installed and worse, when I try rpm -qa I get the
following: 

 error: rpmdbNextIterator: skipping h#    1658 Header V3 DSA signature:
BAD, key ID db42a60e
error: rpmdbNextIterator: skipping h#    1660 Header V3 DSA signature:
BAD, key

I tried then to fix db with rpm -vv --rebuilddb but what I get is a
segfault. I found a similar case in
http://lists.freshrpms.net/pipermail/rpm-list/2003-September/005881.html
but unfortunately no replay has been given to this issue

Any idea? 
Thanks 
Luca
