Bug#434329: Error when try to setup a local mail account

[Fabiano Manoel de Andrade]

   Hi, I think I've found the "origin" of bug. The crash occurs when I try
to setup a system mail account.  When mail-notification try to detect the
account type the program crash. If I delete the system mail account setup,
mail-notification can back to work.
   Regards.
   Fabiano.
