Title:
  fontforge crashed with SIGSEGV in SCNumberPoints()

Status in “fontforge” package in Ubuntu:
  New

Bug description:
  Binary package hint: fontforge

  It crashed when I tried to generate instructions
  (Hints->AutoInstr->Nowakowski) on the Bitstream Vera Sans font
  (included in Ubuntu).

  I'm using a pre-release version of Hardy (updated 2007-12-28).
