367780 - assertion `ATK_IS_OBJECT (atk_object)' failed

Status: RESOLVED WORKSFORME

(Core :: Disability Access APIs, defect)

Description

[Lynn Monsanto]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.1) Gecko/20060601 Firefox/2.0.0.1 (Ubuntu-edgy)
Build Identifier: version 3 alpha 1 (20070122)

I get two of the following assertion failure messages when I tab to the 
"Prefers to receive messages formatted as:" combo box.

** (Gecko:24790): CRITICAL **: impl_getSelectedChild: assertion `ATK_IS_OBJECT (atk_object)' failed

Down arrowing through the combo box popup gives the above message for the "Plain text" and "HTML" entries.

at-poke shows that only one menu item "Unknown" exists in the combo box.

This is a high priority bug because Orca (or any other assistive technology" cannot present the combo box information.  

Reproducible: Always

Steps to Reproduce:
1. Enable accessibility on the desktop
2. Launch the Address Book - New Card dialog
3. Tab to the "Prefers to receive messages formatted as:" combo box
Actual Results:  
Assertion failure seen and no speech for the combo box.

Expected Results:  
The combo box should not fail in reporting combo box information

> 1. Enable accessibility on the desktop

Doesn't happen on 3.0a without accessibility enabled. Therefore it's more likely an accessibility problem -> moving to core/Disability Access APIs.

In my box, at-poke shows a menu "Unknow" as the Combobox's child, and the three combobox options are exposed as menu items of the menu "Unknow".
