> jimm, any ideas?

I strongly suspect the child process is failing to send a message before this one that tells the parent about a piece of the accessibility tree that this message wants us to use.  Then when we do get this one it seems bogus because it refers to objects we don't know about.  Unfortunately its really hard to know more than that without reproducing.  It might be fixing the missing message causing bug 1272706 fixes this too, but there might also be other problems.
