 Fixed (or, at least, worked around)!
Well, since the breakage appeared to be occurring inside Berkeley DB, I tried disabling the "db" entries in /etc/nsswitch.conf. That was the ticket.
I'm not sure if those entries in nsswitch.conf are standard on Ubuntu Feisty 7.04, because this machine has been dist-upgraded several times.
Anyway, all is working now! |
