Hi Johannes, thanks for your report.

I'm the one who proposed the use of /bin/bash, so I'm kind of
disinclined to agree on switching back. ;) There were valid reasons for
making that change.

Can't help thinking that you ask for trouble by excluding /sbin from
$PATH, but possibly it's not just a mistake.

Other ways, besides those you mention, to deal with this bug might be:

* Change the upstart files so they call the upstart bin with full path.

* Add some condition to the .profile file in /etc/skel so it does not
  source ~/.bashrc when sourced by a DM.
  ( Got that idea from http://askubuntu.com/questions/591937 )

Title:
  Xsession crash after login (fix for #678421 breaks)

Status in lightdm package in Ubuntu:
  New

Bug description:
  According to changelog.Debian from version 1.12.3 on 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 source ~/.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
