Comment 15 for bug 1286766

[ubuntu 14.04-64bit on virtualbox.]
confirmed Observed result:
You arrive at the users desktop but background icons are not shown.
A blank dialog pops up momentarily then a crash report dialog.
The blank dialog periodically pops up again (as nautilus attempts to restart).

[enable trusty-proposed & install nautilus.]
$ apt-cache policy nautilus
nautilus:
  インストールされているバージョン: 1:3.10.1-0ubuntu9

[login testuser]
pop up "Oops! Something went wrong." dialog. (does not repeat momentarily.)
---------------------------------------------
Unable to create a required folder. Please create the following folder, or set permissions such that it can be created:
/home/testuser/.config/nautilus}
---------------------------------------------

click "ok" button. --> pop up dialog cleare.
start nautilus. --> no problem.
open terminal & delete .config/nautilus
relogin testuser --> auto created ~/.config/nautilus directory & no pop up dialog.

Is this result correct?
