loadComponentFromURL into _top frame at startup crashes LO

Hi,

this post is somehow related to "open files automatically", but a bit more specific.
http://nabble.documentfoundation.org/open-files-automatically-td4149584.html

When I load a component in an already loaded LO, following code works inside an extension:
URL="private:factory/swriter"
desktop.ActiveFrame.loadComponentFromURL(URL,'_top','',())

But when I try to do that on startup of LO, LO crashes.
I used an EventBroadcaster to start the code, like this:

eventb = ctx.getByName("/singletons/com.sun.star.frame.theGlobalEventBroadcaster")
eventb.addDocumentEventListener(listener)

and in the listener:

class Doc_Event_Listener(unohelper.Base,XDocumentEventListener):

     def documentEventOccured(self,ev):

         if document.Name == '':
             document.Name = 'xxx'

             URL="private:factory/swriter"
desktop.ActiveFrame.loadComponentFromURL(URL,'_top','',())

It doesn't matter if I set _self or _top or _parent, LO always crashes. Whereas when I use _blank or _default, it works, but the document gets opened in another window, what is not, what I want to reach.

I tried it on OO also, slightly different with a TopWindowListener, and it works.

Does anybody have an idea about what is going on and if it is solveable in another way?

Regards,

sorry, forgot some code in the listener.m it should be:

class Doc_Event_Listener(unohelper.Base,XDocumentEventListener):

     def documentEventOccured(self,ev):

         if ev.EventName == 'OnLayoutFinished':
             if document.Name == '':
                 document.Name = 'xxx'

                 URL="private:factory/swriter"
desktop.ActiveFrame.loadComponentFromURL(URL,'_top','',())

One irritating thing I found out:
Although the listener is called with "onLayoutFinished" the desktop still doesn't have an
ActiveFrame. It seemes to be set afterwards.

When I create a component enumeration, I can see the upcoming component, but it isn't set yet.

Any ideas, how to receive an event after it is set?
