Trevor, David, do you know what could have caused this ?

After bug 1329814 a DocAccessibleParent can be shutdown by the parent process
before a content process has started shutting down the document that
DocAccessibleParent represents.  That means the content processcan send an
event from a live document to a DocAccessibleParent that has already been
destroyed.
Attachment #8826702 - Flags: review?(bugs)
This shouldn't be necessary because shutting down all the proxies and child
  documents should already do it, but we might as well be sure.
