The problem is with the recently introduced mRecentCollectionMenu.
This is a mapping between the action type and the RecentCollectionAction. There
is an entry added to the map every time the menu is about to show.

1) first problem: even though the map holds a smart pointer, QPointer to the
RecentCollectionAction (should be QWeakPointer), when the pointer value is
read, it is not checked for null, that's why it crash.

2) the reason I didn't fix it simply by checking the value for null is that I
see no place where entries are removed from the map. This looks wrong to me, so
I let Laurent go through his code and fix it. :)
