A fix was pushed to emacs-26:

d63c9a9..: Stefan Monnier 2017-11-11 * lisp/minibuffer.el: Install a workaround for bug#16274
  commit d63c9a96f51fd4d723dc66a6cc0a8a0a04c8ce6c
  Author: Stefan Monnier <monnier <at> iro.umontreal.ca>
  Ref:    emacs-26~5
  Date:   Sat Nov 11 10:25:20 2017 -0500

  * lisp/minibuffer.el: Install a workaround for bug#16274

  * lisp/minibuffer.el (completion--nth-completion): Avoid signaling an
  error when `md` is applied to another table.

It should already be merged into master, so I'm closing the bug.
Thanks for reporting this issue.

Steps to reproduce:

$ cd /
$ emacs -Q
M-x icomplete-mode
M-x rgrep foo RET e

(Where ‘foo’ is arbitrary text and ‘e’ is the first letter of one of possible completions.  In this example that would be ‘etc’.)

Got an ‘Error in post-command-hook (icomplete-post-command-hook): (cl-assertion-failed (functionp table))’.

Backtrace:
