This simply can't happen if the user follows the book to the letter.
Look at http://www.linuxfromscratch.org/lfs/view/development/chapter04/addinguser.html:

useradd -s /bin/bash -g lfs -m -k /dev/null lfs

See "bash" here? On the next page, /bin/bash is also explicitly called
in ~/.bash_profile.

So: the bug report is invalid.
