Bug 176798 – [GTK] AX: Two layout tests crash with error "atk_object_get_attributes: assertion 'ATK_IS_OBJECT (accessible)' failed"

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: Accessibility

[Michael Catanzaro]

After enabling G_DEBUG=fatal-criticals for our layout tests, the following tests:

accessibility/aria-tables.html
accessibility/table-sections.html

Are now crashing with the following error:

STDERR: atk_object_get_attributes: assertion 'ATK_IS_OBJECT (accessible)' failed

Updating expectations accordingly. Here's a crappy backtrace from accessibility/aria-tables.html:

Pretty sure this is a duplicate of 179837. Marking as such since the tests are now passing "unexpectedly" for me with my proposed fix for that bug.
