Code review comment for lp:~nick-dedekind/unity/lp1055995.launcher-icon-expo-terminate

From the Stack-trace in the bug, it looks like the quicklist has been destroyed; in which case the LauncherIcon has been.

In theory, the following could have happened, although I had not been able to reproduce it:
1) Workspace switcher is opened
2) User right-click on icon for quicklist.
3) Expo is closed by quicklist request.
4) Aysnchronously, the icon is removed from the launcher (possibly uninstalled/user removed ?)
5) quicklist is opened.
