Please read that mail about cleanup().

Put click_chatter messages in your cleanup() method. Print out the
particular element pointer ('this'). You will see that the cleanup() method
is being called on *two different elements*. One of them (probably the
prototype element stored in the lexer, as I explained in email earlier this
week) is getting called with cleanup_stage CLEANUP_NO_ROUTER.

Obviously you wrote a bad cleanup() method. Pay attention to the
cleanup_stage argument. Do not attempt to delete random memory that you
never actually allocated (because configure() and/or initialize() was never
called). Do not dereference null pointers. Do not call "Packet::kill()" on
packets that do not exist.
