bug#19336: 24.4; icomplete-mode error when icomplete-show-matches-on-no-input set

[Max]

Hello,

Starting with emacs -q in a directory containing files a, b, c and d.

Typing:

M-x icomplete-mode
M-: (setq icomplete-show-matches-on-no-input t)
C-x C-f
C-a C-k

produces:

Error in post-command-hook (icomplete-post-command-hook): 
(invalid-function (#("a" 0 1 (face (completions-first-difference))) 
#("b" 0 1 (face (completions-first-difference))) #("c" 0 1 (face 
(completions-first-difference))) #("d" 0 1 (face 
(completions-first-difference))) #("./" 0 1 (face 
(completions-first-difference))) #("../" 0 1 (face 
(completions-first-difference)))))

This does not occur when icomplete-show-matches-on-no-input is nil.

Regards,

Max.

(I'm going through old bug reports that unfortunately have not received
any responses yet.)

I'm unable to reproduce this bug in Emacs 27, so I'm guessing that it's
been fixed in the intervening years, and I'm closing the bug report..
If you're still seeing this bug, please reopen this bug report.
