Comment 1 for bug 589715

So symlinking motd+shell definitely fixes the issue on upgrade. However it wouldn't fix the following situation:

A user who uses a tty does the following:
1) Makes changes that have the effect of changing the contents of .byobu/windows to something similar to:

# Default windows examples
#screen -t notify-osd -M tail -f $HOME/.cache/notify-osd.log
#screen -t top top
#screen -t web elinks
#screen -t shell motd+shell
screen -t opps does_not_exist

2) User has launch on login check.
3) User logs out.
4) User logs in.
5) User is immediately logged out when does_not_exist fails to exec.

I'm not sure if there is really anything that can be done about this or if it is really a bug. I just thought I should mention it. I've tested this situation on my Ubuntu desktop, and am not sure how it would play out on ubuntu-server yet.
