Ticket #11 (defect)

I am trying to use my tny-camel-send-queue subclass (which only overrides the get_sentbox and get_outbox methods), but I am seeing some crashes. Here are three stack traces; the one in the middle during 'online' state; when in online state, we seem to get that stacktrace every time; but in offline mode there are different possibilities (the other two traces, and prob. more).

Any hints?
