You haven't given us enough information about your setup, so I'll have
to do some guessing.

You're probably sourcing your ~/.bashrc from ~/.xsession or from
~/.gnomerc, and you're probably sourcing /etc/bash_completion from
~/.bashrc.

GDM executes the session script under /bin/sh, which is not necessarily
bash.  /bin/sh may barf on bash-specific commands such as those found in
/etc/bash_completion.  If it barfs, your xsession script gets terminated
and you cannot log in.

No, just make sure you don't run it from your session script.

I've taken two precautionary measures: in my ~/.gnomerc I have

  # do not abort the script on first error, that makes login impossible
  set +e
  source ~/.bash_profile
  set -e

and in my ~/.bashrc (which is sourced from ~/.bash_profile) I have

  # If not running interactively, don't do anything
  [ -z "$PS1" ] && return

before I source /etc/bash_completion.

I hope this helps,
