Bug report : vimpager freezes when specifying a directory

[windware-ono]

OS : Ubuntu 18.04 64bit
Shell : /bin/bash
Vim : Vi IMproved 8.0 (2016 Sep 12, compiled Apr 10 2018 21:31:58) (Installed via 'vim-nox' package.)
.vimrc : None
.vimpagerrc : None
Cloned : 8cbddd1

I installed it with sudo make install-deb and when I run vimpager . and specify some directory (which I shouldn't but it can happen accidentally), vimpager freezes and had to be killed with SIGKILL.

The error shown is,

$ vimpager .
head: error reading '.': Is a directory
head: error reading '.': Is a directory
cat: .: Is a directory
wc: 'standard input': Is a directory
sed: read error on .: Is a directory
cat: .: Is a directory
