The problem appears to be related to the type of variable submitted by form.
 When no forums are present the form only lists one option in the dropdown
box: "-- Top Level--" with a value of "-1".  When this is submitted by form
back to the server this becomes the STRING "-1".  The array however is
populated with the INTeger -1.  This behavior is documented on php's website
at
http://us3.php.net/manual/en/language.types.array.php#37535

I verified this by gettype()ing the two variables $value and the keys of
$this->_values in HORDE_BASE/lib/Horde/Form.php on line 2081.  Since this
could theoretically be a larger problem in forms which use enums with
negative array indices I'm not sure how to proceed.  To solve this problem
for me for now I am coercing the value to an int in AGORA_BASE/editforum.php
on line 49 with the following ugly workaround:
$vars->set('forum_parent_id', (int) $vars->get('forum_parent_id'));

I leave it to the Horde team to decide the proper corrective action.
