ubiquity only mode: close/minimize/restore are on the right edge

[Didier Roche-Tolomelli]

[Impact]
Unity settings daemon has a tendency to crash in ubiquity only install mode. The result is that close/minimize/restore are suddenly shifted to the right

[Test Case]
1. Start the live iso, choose the ubiquity-only installer mode.
2. Wait for some screen, opens some ubuntu control center windows -> you may get a crash (reliably on some machines) in the 30s. This results visually in the decorations button shifting to the right.
3. Install the u-s-d package from -proposed (with break=casper-bottom) on the live and then pursue to ubiquity starting.
4. Redo the some operation then 2 -> no crash should happen

[Regression potential]
The crash only happened on certain machine and only at install time. The fix will be there mostly for the LTS install time then, but still can be useful for any derivatives which don't want that crash to happeN.

Choose ubiquity only mode (here in French).

First, the window decoration are on the left, but after you open any
other windows (like the text entry from the keyboard indicator, or try
to grab a screenshot), any modal dialog in ubiquity (like "apply those
changes to disk") or additional windows started from indicators like
text entry settings for keyboard have their window decoration controls
shifted to the right (see pictures attached).

Looking at unity-settings-daemon, it's <defunct> on the ps list.

unity-settings-daemon is "<defunct>" in the ps list, doesn't look right

[Sebastien Bacher (seb128)]

there is an apport report/segfault in syslog

seems similar to bug bug #1436861

Remove duplicate, we still have the crash despite the u-s-d fix from the 21st
