[turba] Call to a member function hasChildNodes() on a non-object

[vandman]

Hi,

Since I apply the latest update on horde and here on turba (4.2.0), I
can not update the configuration (Configuration is out of date.).

By the way, I did not make any change
to /usr/share/php/Horde/Config.php. It worked perfectly on the previous
update.

Here is what horde tells me:

A fatal error has occurred
Call to a member function hasChildNodes() on a non-object

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] => Call to a member function hasChildNodes() on
a non-object
    [string:Exception:private] => 
    [code:protected] => 0
    [file:protected] => /usr/share/php/Horde/Config.php
    [line:protected] => 212
    [trace:Exception:private] => Array
        (
            [0] => Array
                (
                    [function] => catchFatalError
                    [class] => Horde_ErrorHandler
                    [type] => ::
                    [args] => Array
                        (
                        )

                )

        )

    [previous:Exception:private] => 
    [severity:protected] => 1
    [logged] => 1
)

Thanks for the help.
