Problems getting RT 3.4.4 to work with RTFM 2.0.4

I have RT 3.4.4 installed with RTFM 2.0.4 on FreeBSD with a Postgres
database backend. After I attach an article to a ticket and email it
to a requestor I get the error attached below. The ticket still is
sent to the requestor but the error is slowing down the workflow of
our helpdesk so I was hoping there might be a fix for this.

Thanks.

System error
