Title:
  command-not-found is hiding exception/backtrace when crashing

Status in “command-not-found” package in Ubuntu:
  Confirmed

Bug description:
  command-not-found is telling the user to report a bug but is hiding
  the usefull informations.

  i have a case where i can crash the crash dumper of "command-not-
  found"

  LANG=en  (instead of LANG=en_EN.UTF-8)

  this is crashing the crash dumper and command-not-found can not get
  that informations to display it (should also affect other situations
  where crash dumper is crashed before)

  LANG=en

  vii foo
