Can you reproduce the error and if so, what steps?
Does it crash while loading yast, while loading repositories, or does it crash during SuSEconfig?
Does the error say anything about an SQL database or 'db'?
I have a few things that you may try to fix this.
First, rebuild the rpm database as root:
If that doesn't work, try creating a new rpm databaswe as root:
Also, try manually refreshing the yast repositories(if you can open yast):
-Goto Software section
-Click Software Repositories icon
-Click "Refresh" button at the bottom right of window
-Select "Refresh All Autorefreshed"
Post back with more error/info if you still have problems.
