Thanks for this clear description of the bug! Since there is no object
"scroll of levitation" it follows that you were confused. Now assuming
that it was a scroll of teleportation you read while being confused,
this will have teleported you (but not the purple worm) to some other
level of the cave. An interesting situation arises: you are in the
stomach of a monster that is on another level, and a core dump results.

For those too impatient to wait for version 1.0.2 here is the fix:
