Nautilus is causing a constant flow of GLib-GObject-CRITICAL assertion errors

When Nautilus is open, a constant flow of identical errors are being added to ~/.xsession-errors.
The following error is added every second, constantly, for the period Nautilus is open:

(nautilus:3088): GLib-GObject-CRITICAL **: g_value_get_object: assertion `G_VALUE_HOLDS_OBJECT (value)' failed

By default the "(nautilus:3088):" prefix is not added to the log. This is the result of setting "G_MESSAGES_PREFIXED=all" as an environment variable.

Besides the fact that it renders the .xsession-error file useless, it is quite embarrassing that such an error has been overlooked.

To my knowledge only Tracker added additional Nautilus integration.

Let me know if you need any more information.
