Greetings,

I'm from Hawassa University a place 271Km from capital city Addis
Ababa, Ethiopia. Currently we are moving to use Koha for our Library. I
had upgraded from 2.2 to 3.0 on Ubuntu 8.04 and I was successful using
the manuals for installation and upgrading from Koha-duke site. But when
the librarians are adding items in to the database, it will show us
"production mode - trapped fatal error" . the error in koha log file
states that 

   " [Tue Sep 08 15:59:07 2009] [error] [client ...] [Tue Sep  8
