[otrs] Problems with Postmaster reading certain emails

Hi Lately my OTRS has had problems reading certain emails. When i parse the email through Postmaster.pl, I get this error msg: "perl: prescan_stmt.c:442: rewrite_execute_stmt: Assertion `ph <= imp_sth->phc' failed." Does anyone know why this is happening? I'm running CentOS 4, with perl 5.8.5. In my otrs1.3.3 this is very irritating, since it generates a ticket without an article, which makes all tickets received later not able to be shown. Luckily this is fixed in 2.0.x. Regards Espen Stefansen
