-----------------------------------

    Assignee: Alex Hermann  (was: Unassigned)
      Status: Waiting for Feedback  (was: Triage)

I've looked through the code and based on the backtrace I don't see how it would have actually happened. I think the only way to identify the cause would be to have a console log with debug enabled to show the series of events and actions leading up to the crash.
