> When clicking on a item in a KListWidget, the `executed` signals is not correctly emitted.
> If the system-wide setting is to use single click, only `executed( QListWidgetItem *item )` is emitted (once).
> If the setting is to use double click, `executed( QListWidgetItem *item )` will be emitted twice and `executed( QListWidgetItem *item, const QPoint &pos )` is emitted once, which cause the edit note dialog in Kontact_KNotePlugin to popup a second time right after close in some cases.
