Public bug reported:

According to changelog.Debian lightdm is using "bash for the session to
improve error handling" to fix #678421.

Unfortunately this can break the session start up when the user sets the
$PATH environment variable in ~/.bashrc. Then /sbin might no longer be
in $PATH and /etc/X11/Xsession.d/99cadence-session-start won't find
/sbin/upstart when calling "upstart --user"

The mechanism is the following:

1. /usr/sbin/lightdm-session lines 37-42 source among others ~/.profile

2. The usual .profile of /etc/skel will ~/.bashrc if the shell is Bash
(and not /bin/sh)

3. ~/.bashrc (maybe) is setting $PATH without /sbin

4. upstart --user call fails as /sbin is not in $PATH


Suggested solutions:

* switch back to /bin/sh

* make sure that /sbin is in $PATH

** Affects: lightdm (Ubuntu)
     Importance: Undecided
         Status: New
