Date does save data properly when using conditional fields

The problem that is happening is that somehow when a "conditional" date field is unset that field's value does not properly get stored in the database.

This problem can be observed in the file: date/date_token.inc on line 39:
$item['value'] = trim($item['value']);

$item['value'] ends up being set to array('date' =>)
Here, trim function does not expect an array() to be passed to it.

If I were to set the appropriate condition so that I can edit the date field, then the resulting $item['value'] is not an array.
Therefore, this only happens when the date field is disabled (and possibly when hidden) by a conditional field.
