bug#14446: 24.3.50; completion is no more working in condition-case forms

[Thierry Volpiatto]

Hi,

when trying to complete inside a condition-case form like:

(condition-case nil
    (with-!)

Cursor is at "!"

I have no completion and an error:

Debugger entered--Lisp error: (wrong-type-argument characterp nil)
  lisp-completion-at-point()
  completion--capf-wrapper(lisp-completion-at-point all)
  run-hook-wrapped(completion--capf-wrapper lisp-completion-at-point all)
  completion-at-point()
  call-interactively(completion-at-point nil nil)
  command-execute(completion-at-point)

If I try to complete (with-!
outside of the condition-case form I get completion starting by "with-"
as expected.

Also this is working as expected in Emacs-24.3.
