Ok, this was the cause of the error. Now, ACLs seem to work, but there
seems to be a hardware error instead :-(

Ok, I have found that.

Yes, I know. There is 1.1.5 on both source and destination machines. I
only test the behaviour of 1.1.15 in addition on a third machine.
And on both machines with 1.1.5 installed I do not see any tables
printed at all.


The following seems to indicate a hardware error, doesn't it?
