The fix for https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/678421
leads to `.profile` being sourced by bash instead of dash. This leads
`.bashrc` being sourced indirectly via .profile. IMHO, `.bashrc` should
not be sourced even *once* in this situation. I suggest that sourcing
.profile actually be done with BASH_VERSION unset:
BASH_VERSION= . "$CONFIG"
At the very least, a check should be done whether bash is the user's
login shell. It can be done thus:
[ "$SHELL" != "/bin/bash" ] && BASH_VERSION=
. "$CONFIG"
utilizing `$SHELL` given it stores the login shell
(http://unix.stackexchange.com/questions/45458/why-shell-doesnt-change-
when-i-run-new-shell).
