Up to date SLES 9.0 segfaults with local source

Hi, I created seven local directories (/var/cds/cd1/, ..., /var/cds6/, /var/cds/sdk1) and an index with genIS_PLAINcache to have a local source of packages. I needed it for yast cd-creator. When adding this source in YaST, it segfaults when I try to install software. I used YOU to keep my SLES up to date. What can I do ? Thanks for your help, Pierre
