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

[Simon Woolf]

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)
