Bug Description

This monday (2011-02-28) the AtkSelection support on the launcher was launched, so the selection changes are properly exposed, and also notified with orca.

But yesterday I realized that this stopped to work on orca, and checking the orca debug file I found things like this:

vvvvv PROCESS OBJECT EVENT object:state-changed:focused vvvvv
OBJECT EVENT: object:state-changed:focused detail=(0,0,0)
app.name='' name='None' role='tool bar' state='focusable' relations=''

Empty application name for an object.

OBJECT EVENT: object:state-changed:selected detail=(0,0,0)
app.name='cdrom0' name='cdrom0' role='push button' state='' relations=''
^^^^^ PROCESS OBJECT EVENT object:state-changed:selected ^^^^^

Taking as the application the same object.

After look at this, I printed the parent of any of those objects, and were NULL, assuming that it is already on the application object. So it seems that in order to get the application object, it starts to iterate for his parent. This is debatable but it is not the point here, are the parent is checked for other reasons.
