Code review comment for lp:~brandontschaefer/unity/possible-crash--fixes

So im tracking down the crash that wasn't fixed by this branch. Here are the only 2 crashes now from UnityPlugin and Wobbly Windows:

Caused when enabling/disabling Unity Plugin in ccsm
bamf_matcher_on_view_opened:

normal backtrace

Caused when enabling/disabling Wobbly Windows in ccsm
bamf_matcher_on_view_closed:

normal backtrace

What happens is either OpenView is emited twice on the same window or the CloseView is called twice on the same window. It was always the same window for open, or the same for close (if you cause the crash multiple times).
