Before 13.2 bash-completion was usually nor present, so it did not matter. In
13.2 bash-completion is pulled in by systemd-bash-completion, and
/etc/bash_completion.d is processed after bash-completion is initialized.
acroread.sh should check whether _filedir is already defined; cf.
/etc/bash_completion.d/quilt.sh.

Closing as not a bug.
