Public bug reported:
What I did:
Press X on a window that wasn't responding. Got tired waiting for the
"Force quit?" dialog to show up. Ran "xkill" and pointed on the window.
What I expected to happen: the non-responding application is killed.
What happened instead:
Just before I ran "xkill", the "Force quit" dialog appeared, thus the xkill
command ran on the Force Quit dialog rather than on the application window.
Apparently, when xkill is invoked on a Force Quit dialog, a) the whole unity
process is killed and b) the session crashes! (unsure why). The user is placed
back to the login prompt, i.e. all open applications are closed resulting in
possible data loss.
Possible fix:
a) Run "Force quit" dialogs in a separate process, or otherwise disassociate
them from the unity process.
b) ?
Reproducibility: happens 100% of the time when running xkill on a "Force
quit" dialog.
