Attachment: patch

atkObj could be null when fire SHOW/HIDE event for text, just return NS_OK for such case.
also add assertion in atk/nsDocAccessibleWrap::FireToolkitEvent

Please see bug 378468 comment #6 to 8

Comment 3

For text, we don't fire children_changed for it (text is not child accessible), we fire text_changed. That is not covered by bug 378468.

So I think we can either just fix it in this bug, or merge this patch into Surkov's patch for bug 378468.

I'm not sure how this fits in with Surkov's SHOW/HIDE rewrite.
