Comment 3 for bug 42947

I'm getting the same error on dapper (Linux version 2.6.15-23-386 (buildd@rothera) (gcc version 4.0.3 (Ubuntu 4.0.3-1ubuntu5))) on a Duron with the latest updates.

------------------

I've tried removing postfix, deleting every reference i can find about it and reinstalling and it continues. I've tried on a VM install of dapper and do not have the same problem.
