Bash completion is initialised in /etc/bashrc, which should only be read by
interactive shells.  Maybe you're sourcing it from your ~/.xsession script?

Also, Bash's process substitution feature ("<(...)") is not available when Bash
is invoked as "sh".  So you may not want to use "#! /bin/sh" for ~/.xsession.
