Hello Horde mail list,

upon clicking "Reply to all" to reply to a maillist email, I was greeted by
my horde framework with the following error:

  A FATAL ERROR HAS OCCURRED

  CANNOT USE OBJECT OF TYPE HORDE_MIME_HEADERS AS ARRAY

  1. Horde_ErrorHandler::catchFatalError()

  DETAILS

  The Full Error Message Is Logged In Horde's Log File, And Is Shown Below
Only To Administrators. Non-administrative Users Will Not See Error
Details.

  ErrorException Object (     [message:protected] => Cannot use object of
type Horde_Mime_Headers as array     [string:Exception:private] =>

       [class] => Horde_ErrorHandler                     [type] => ::
              [args] => Array                         (

  [severity:protected] => 1     [logged] => 1 )
What is it exactly and what does it means?

Thanks
