well I will just take the risk now.
I need to find a solution NOW. In the worst case I will have to copy the status of yesterday back onto the first harddisk - I have two harddisks and did a dd from a to b before upgrading yesterday - but it would take a few hours at least.
Hm. It does not seem to work. I still get the segmentation fault.
I have also downgraded sasl now without success.
