Michail Vourlakos 61016444fb dont crash when changing layouts
--occasionaly when the user was switching
layouts it could get some crashes. It looks
safer to unload first the Latte::Views objects
and their corresponding containments afterwards.
I tried in my system to switch multiple layouts
in plenty different configurations and I could
not get a crash. This patch should fix the
mentioned crash report if that was the root
of the issue.
