yes. i've found it only appears if "subdir" is not world read- and
executable:

# ls -ld /etc/skel/subdir/
drwxr-xr-x  2 root root 4096 Mar 14 15:44 /etc/skel/subdir/

# adduser --home /home/test103 --shell /bin/bash
--ingroup users --disabled-password --gecos "bla,,," test103
Adding user `test103'... 
Adding new user `test103' (3280) with group `users'.
Creating home directory `/home/test103'.
Copying files from `/etc/skel'

but

# chmod go-rX /etc/skel/subdir/
# adduser --home /home/test104 --shell /bin/bash --ingroup users   
--disabled-password --gecos "bla,,," test104
Adding user `test104'...
Adding new user `test104' (3282) with group `users'.
Creating home directory `/home/test104'.
Copying files from `/etc/skel'
Use of uninitialized value in symlink at /usr/sbin/adduser line 695,
<FIND> line 190. symlink: No such file or directory
Cleaning up.
Removing directory `/home/test104'
Removing user `test104'.
userdel: unable to lock password file

# ls -ld /etc/skel/subdir/
drwx------  2 root root 4096 Mar 14 15:44 /etc/skel/subdir/
