initKeyboardEvent attempt

This is what I've got for the DOMKeyboardEvent so far.

However, I'm having a problem with WebKit that is likely related to this code.
I'm creating a DOMKeyboardEvent with [DOMDocument
createEvent:@"KeyboardEvent"], then I use the initializer from the patch with
the following values (from the XML my app reads):

   <event>
      <target domindex="0,1,0,5,2,0,0,1,1"/>
      <property name="type" value="keypress"/>
      <property name="class" value="KeyboardEvent"/>
      <property name="bubbles" value="true"/>
      <property name="cancelable" value="true"/>
      <property name="detail" value="0"/>
      <property name="ctrlKey" value="false"/>
      <property name="shiftKey" value="false"/>
      <property name="altKey" value="false"/>
      <property name="metaKey" value="false"/>
      <property name="keyIndentifier" value="U+000041"/>
      <property name="keyLocation" value="0"/>
   </event>

(For the abstract view argument, I pass NULL. Maybe that could be the
problem...)

Then I dispatch this event to a <input> field in my WebView. When I do this,
WebKit crashes:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000004

What's wrong with the initializer?
