Bug#636100: Provides no useful feedback when window manager fails to start

[Josh Triplett]

Package: gnome-session
Version: 2.30.2-3
Severity: normal

If the window manager (such as metacity) fails to start, gnome-session
logs to ~/.xsession-errors, but otherwise provides no useful feedback to
the user about why their session doesn't work as expected.
