Up to date Novell Linux Desktop segfaults with local source

Hello, I created three local directories (/var/cds/cd1/, ..., /var/cds/cd3) and an index with genIS_PLAINcache to have a local source of packages. I needed it for yast cd-creator. When generating the index, I've got the following errors : 'error: no dbpath has been set' 'error: cannot open Packages database in' When adding this source in YaST, it segfaults when I try to install software. I used YOU to keep my NLD up to date. What can I do ? Thanks for your help, Pierre
