You are aware of [[m:Help:Inputbox]]

Do you have code to check that the user is actually allowed to create 
the article? Article::insertNewArticle() doesn't do this (in 1.5 or 1.4).

The sound of the error would indicate that you already have an article 
by that name (ie, your extension should check if the article exists 
before working). I also noticed that the cur_title is '' (empty string), 
so the article will likely be inaccessable.

Is ChangeControlExtension.php your thing?

The EditPage class if you really feel like having kludges and hacks around.
