This is a race condition; it happens if you manage to interrupt command-not-found before it's managed to import sys.

Perhaps the exception handler should import sys again?

This bug was fixed in the package command-not-found - 0.2.46ubuntu6

command-not-found (0.2.46ubuntu6) precise; urgency=low

  * Import sys again in command-not-found's KeyboardInterrupt handler
    (LP: #864461).
  * Forcibly remove /usr/lib from the start of sys.path to avoid unsightly
    ImportWarning noise (LP: #983875).
  * Update to current precise.
