Bug description:Calling enchant_broker_get_dict_path before set_path crashes php

Description:
------------
Whenever I try to call (the undocumented function)
enchant_broker_get_dict_path before enchant_broker_set_dict_path my PHP
instance crashes.

My php.ini contains the following entries:
enchant support	enabled
Version 	1.1.0
Libenchant Version 	1.5.0 or later
Revision 	$Revision: 298870 $

ispell    Ispell Provider 	C:\PHP\libenchant_ispell.dll
myspell   Myspell Provider 	C:\PHP\libenchant_myspell.dll 

Test script:
---------------
<?php
$broker = enchant_broker_init();

enchant_broker_get_dict_path($broker, ENCHANT_ISPELL);
?>

Expected result:
----------------
Either false because no dictionary path is set yet or an empty string or
some kind.

Actual result:
--------------
