Title:
  16.04 regression: exceptions in ruby code in plugins have started
  causing vim to segfault

Status in vim package in Ubuntu:
  Expired

Bug description:
  In 14.04, an exception in the ruby code of a plugin caused the error
  to be printed to stderr, after which vim would launch, skipping the
  offending plugin:

    Error detected while processing /mnt/terra/home/simon/dev/vim-livecoding/plugin/livecoding.vim:
    line   37:
    NameError: undefined local variable or method `undefined_method_causing_an_exception' for main:Object
    Press ENTER or type command to continue

  But in 16.04, the same thing causes vim to segfault:

    Vim: Caught deadly signal SEGV
    Vim: Finished.
    Segmentation fault (core dumped)
